Where would you use this Smart Surface Table?

I was forwarded this video about Microsofts tabletop technology by Rob Balmer of the Doubletree Hotel San Jose and I wondered how you might use it at an event. Of course the video shows the different ways business could use it but what about something interactive for an event. They say it will eventually have smart surfaces everywhere which really bends the imagination. Think about walls, tables and counters. I wonder what the rental prices will be for these tables?

One thing is for sure the future looks like fun.

How would you use it?
