Mixed-reality conference

Via Troy McMonaghy, news that NASA is putting a live feed of an entire four day conference into Second Life:

NASA Ames (in Silicon Valley) is currently hosting the Next Generation Exploration Conference 2.0. They’re doing something really ambitious… a live video feed of the whole four-day conference into Second Life – so people at the NASA Sun Amphitheatre in Second Life (on the ‘NASA CoLab’ sim) can watch it realtime. Better yet, they’re showing the SL audience on a big screen in the actual conference. They’re also taking questions from people in SL and relaying them to the speakers or panels in California.

Troy posts a great picture of the event:

Why aren’t more conferences made available this way?
