How to write a Letter of Intent?
Also known as: letter of intent to bid, letter of intent to submit a proposal, letter of interest, letter for expression of interest to bid, proof of intent letter, or expression of interest letter.
What is a Letter of Intent?
Definition of a Letter of Intent
A letter of intent is basically a written statement expressing the sender's intention, should certain circumstances arise, to take or forgo some action, like entering into a future agreement with the recipient, or, more generally, carrying out business activities mentioned in the letter of intent.
The letter of intent in the solicitation process
In the solicitation and selection context, the letter of intent tells the company issuing the Request for Proposal (RFP) that you are interested not only in submitting a proposal in response, but also in receiving all RFP updates and modifications. It's also referred as a letter of intent to bid or a letter of intent to submit a proposal.
Is the letter of intent a binding document?

A letter of intent is neither an offer or a contract. Thus, it doesn't oblige its writer and, consequently, cannot be enforced. Although the letter of intent is not, by essence, a binding document, we may often find at the bottom or, even worse, in the body of the letter of intent a paragraph stating and reinforcing the non-binding character of the letter of intent. This mention is usually inserted under the pressure of a legal attorney, or any legal advisor or department considering the letter of intent as a binding document, and not as a mere agreement to agree in the future, unless a mention states the contrary.
"In order to be a valid and enforceable agreement, a document must contain certain essential legal provisions and must not leave either undecided or to be determined at some time in the future any aspect of such essential legal provisions. If these essential elements are not present, then the document is not a binding one and is often referred to by courts as an agreement to agree or a letter of intent, both of which are not enforceable as contracts. (...) Thus, the letter of intent is essentially a legally worthless document."

Writing a Letter of Intent
It is highly recommended that you to read the suggestions below in order to properly and successfully write the letter of intent.
Use a formal letterhead and do not handwrite the RFP letter of intent.Use templates and samples provided in your FREE RFP Letters Toolkit to create your own letter of intent.
First, indicate your interest in the RFP you received, and acknowledge the deadline for the proposal you will submit.
Next, remind the RFP issuer that you are, at the same time, interested in being kept informed about any modification related to this project, i.e. the RFP document itself.
Finally, close the letter formally with "sincerely" or a similar polite expression. Sign your name and title. Be sure to provide correct, complete contact and reference information for future correspondence.
Do not forget to send the letter of intent via certified mail.
Since things sometimes get a little more complicated than usual, remember to consult a lawyer for further information before doing anything.

Application Model Initially, we are making the big assumption here

Application Model Initially, we are making the big assumption here, that the model run at each site/host is the same, and that the only differences are POVs and the user at each host. However, it is not necessary for all users at all sites to ``see'' all objects. In fact, real estate probably precludes this. This means that certain (large) optimisations are possible in terms of delivering operation/messages to each host.
The set of typical operations between a VR application and the underlying system range from moving point of view to moving objects themselves and altering the attitudes.
A more advanced approach, one could consider sending trajectories around, and having receivers apply the model world to the object. (eg. gravity, wind, friction, etc etc).
Messages may be idempotent (describe an absolute position for an object, or position and velocity, and so on), or not (maybe they just say how far the object has moved).
Interactions between users of a distributed VR application are complex. An object must in some senses have an "owner". This may be the user at a site (e.g. if the object is the POV itself, or the glove/pointer, etc), or an object currently under the control of a user.
Thus we should associate a set of objects (and users) with a portion of the multicast address space - the idea is that a user is in some locale and that only operations relative to that locale need be delivered to their system.
Furthermore, there most be some notion of ``real'' virtual world distance. The set of objects in VR in a locale that are ``near'' a user are subject to interactions which can reasonably be modeled without having to worry about propagation delay across the net. Beyond some distance, and the time to get a message from the originator of the action to the hosts that a set of POVs that include this locale may simply be too high to consider. For example, imagine playing catch in a virtual world simulated between two machines on the net. The time for the ball to reach the ground is less than the time for the message to cross a terrestrial line more than a few thousand miles.
However, it may be possible to introduce some element of representation of distance into the user interface - two approaches suggest themselves based on physics models of the real world:
1.
Uncertainty - as an object gets further away, we can introduce less certainty about its position (note that the SRM protocol above gives us enough information to do this accurately!).
2.
Relativity - we could warp spacetime in the virtual environment to produce a similar effect to gravity - action at a distance could become much slower.
Given this, different VR applications may need to relax a different one of the four constraints, possibly at different times. In fact, we can envisage single applications that need to relax different constraints for different objects at different times.
