I had a question/advise about setting up a video conference/chat (with a/v) between my Mac and my girlfriend's PC. If I plan on picking up an iSight and use iChat AV, what should I recommend my girlfriend use for her PC? I was going to pick up a Logitech WebCam 3000 but then I don't know which PC software to use that would be compatible with iChat AV. Any recommendations on software compatible with iChat? Should I even use iChat AV? Thanks!!
