Blizzard considering at home demos, and Xbox Live viewing for next blizzcon.

I just got word via a survey that Blizzard is considering allowing users of next Blizzcon to play games during blizzcon from home along with watching the stream from XBOX Live. See the screenshot below. This is super exciting for people like me, who are getting sick of the lines but would gladly pay to get my hands on demo versions of their latest games. If they used a service like OnLive, I think this could work out perfect.
