John's changes in respect of vendor and solution neutrality are perfectly fine from my perspective, so I won't be suggesting any substantive modifications. (Note however the removal of the word "proprietary" in the final paragraph, which may be substantive, depending on what was intended --- I believe it was there simply by mistake, since the remainder of the paragraph did not address the subject). I have tidied up several English, grammatical or spelling details for the sake of better presentation though, and I also have a comment to make about the timeline at the end: > > Description of Working Group: > > Virtual Worlds and other Massively Multi-Party Online Applications are of > increasing interest to the Internet community.

That implementation exposes the mapping of regions to individual machines and/or simulators, and hence conflates our very important notion of abstract communication endpoints with the very non-abstract and non-generic details of their exposed machinery. As a result, I do not believe that the publication of a specification for inter-simulator communication is in any way related to our work here: virtual worlds may not even have simulators, let alone inter-simulator communication. I am of course in no way discouraging the publication by Linden Labs of their internal details. Quite the opposite, I believe that it would be good for them to have additional eyeballs trained on those details, and I will read that material avidly. But that work bears no direct relationship to the vendor-neutral, inter-world protocol suite that we are developing here, and therefore while it may be a milestone for Linden Lab, it is not one of ours.
