VOS (plus applications) is now available at <a href="http://interreality.org">http://interreality.org</a>
Major changes include: A major bottleneck in the message processing code has been removed in this release, so that the VOS is quite fast now. In Ter'Angreal (the 3D client), you will enter the world almost immediately and objects will appear as they are downloaded. There is now support for issuing complex queries about an object structure on a site with the results streamed back. You can now write world servers in Perl. There is a new demo world, "Conic Temple". VOS has been ported to Microsoft Windows, and some parts of the protocol have been tweaked to be more efficient.
