I'm currently putting together a report for a client on virtual world technology. Searching through the noise I've come across a couple that look good (including the obvious Second Life):<p><a href="http://www.smartfoxserver.com/" rel="nofollow">http://www.smartfoxserver.com/</a> - Can create 3D worlds through Flash<p><a href="http://www.multiverse.net/" rel="nofollow">http://www.multiverse.net/</a> - A good development platform but not quite ready yet, I don't think<p>Does anybody know of any others that might be of use? I've searched long and hard and can't find much that I like.<p>Also...while I'm at it, does anybody know how many players can realistically be supported in the Source Engine? I know the "maximum" is 32, but is that just a hardwired restriction or can it be revoked?

Thanks guys, these look like good options, but is there anything more like Second Life that doesn't tie you into it's own system, like Linden Labs does?
