[sldev] Call for requirements: ISO MPEG-V (mpeg for virtual worlds) Deadline: July 16, 2008

[Bj Raz]

I think this doesn't' fit in what is being said at this moment, but this is
what I see as what the new standard doing.

What I see here is the possibility for inter continuity between objects
within other virtual worlds, like WoW and characters to come and interact
with in SL.  Now you are breaching 3D worlds and making them one world. each
world can go to SL.  That is what I see.  Avatar transport between 3D
worlds.  Data encapsulation, from one platform (virtual world) to another.
 WoW -> SL
