Was at an Internet2 meeting where we used a Polycom SoundStation IP 4000 to bring in remote people to a large room of people. It worked surprisingly well.
About $750 each.
I've ordered two units - should be here at the end of May. Need to test and then look for people to try using them - will check with Henry Jenkins to see if he's interested. Any other ideas on who would use them? We could also see if audio-visual might want to co-sponsor some free trials?
