I'll add to Jim's commentary that I did also use the free Qik Video Connect app on my iPad2. The app is not designed for the iPad - it's just the iPhone app running on the iPad2 - but it did work perfectly fine to make and receive video calls. In the multiple calls to Jim I spoke with him from both my iPhone and iPad2.
I did not test out the live streaming due to the fact that I was quite sick and did not honestly want people to see me on video! :-) I'm looking forward to trying live streaming, though, at the next event I attend.
At some point I will write up some more of my thoughts, but for now, head on over and read Jim's...
