The pre-meeting to big industry conferences like the Virtual Worlds Fall 2007 convention in San Jose is often more important than the actual pre-set speeches and trade booths. And from various Twitters and Facebooks and hotel lobby chit-chat, the word on the street is that the pre-meeting involved a closed session of game and world makers like Linden Lab and Metaplace together with large companies like IBM, Cisco, and Samsung about interoperability — starting the conversation about making standard protocols for 3-D virtuality on the Internet, and ultimately realizing the geek dream of walking between worlds, of having one identity or one log-on to reach the soon-to-be numerous virtual worlds, and being able to port content among the worlds.
