REALLY old news on this one. This is not your usual lame-o bundled one-to-one webcamware like Netmeeting, etc. This is actual multi-participant video conferencing software that you can slap on any web page.

This idea is sufficiently retro that it almost doesn't even qualify as new. After all, Yahoo started out as little more than a list of categories, from which users self-narrowed the search on the front-end, after which users could either browse, or search more specifically. It's seeing a resurgence lately, with a few "new" twists like tagging; as if tagging could still be considered novel; but anyway you look at it, you're Too Late, Somebody Else is Already Doing That. E.g., take a comparative look at accoona - News Search - "Net Neutrality" versus Kosmix - US Politics - "Net Neutrality". 
That would be the World Transhumanist Association (WTA) working on incomprehensibly crude, yet nonetheless essential early conceptualization of this potential posthuman environment in Second Life.
