This year CommunityOne is going to include live streaming of the sessions. The technology is uStream.TV and it worked very well for me when I tested it earlier.

I've been looking for something like this for a couple of years and, if it goes well today, I have plans to use it for live events (already created the TA Channel).

Today's CommunityOne channels will be at uStream.TV/channel. Check it out and let us know how it works for you.
