I have been experimenting with my Microsoft LifeCam NX-6000 webcam:
It clips to the top of my notebook screen and I got it to do more interactive chats/meetings and to record screencasts that I make with Camtasia Studio. I have found that I get better audio going through my computer than through the camera (which has a microphone). Since I work remotely (from my home office) most of the time, I will start trying to use it to liven up my LiveMeetings, Office Communicator, and Live Messenger chats.
If anyone has anything related to Microsoft developer technology, especially Silverlight and Groove (my two favorite technologies at the moment) that they want to chat about please send me a IM via : my Live ID is [passport at charette dot com].
