I have a powerbook, but recently got a nice dv camcorder, and have it all connected to use w/ everything. I love using it to talk to my other friends w/ iSights and such, but in the new iMac, it says that you can do a One Way video chat, so just your image is shown. I would love to do this to some other people, but is this new in the iMac's iChat (I doubt it?). So how do you do it? I really want to know!! Thanks
