I'm looking into setting up my girlfriend (PC) with the necessary gear for a video link up. I know all the requirements on either side (AIM 5.5 patch etc.), but I was wondering how big/small the windows will be when we finally connect. From the Apple site, Mac-Mac connections can go to full screen depending on connection. What about Mac-PC? For some reason I have a feeling the PC will be able to see me fine (cuz of iSight) but my girlfriend's image on my Mac will be tiny. Anyone have any experience with this? Also, why do you think the min requirement for iChat AV is G3 600 and not 500? Is it cuz of video card memory? I'm curious...and, while I'm on the topic, has anyone had success using eCamm's iChatUSBCam program?
