I tried out the iChat software with the built-in microphone on the PowerBook...totally cool! I've never had the opportunity to experience this type of communication and was thoroughly impressed...giddy comes to mind (kind of strange as I'm sitting next to a phone, but...). I also had the opportunity to use an iSight today - a great little unit. Here's the question: according to Apple's tech notes regarding iChat, AV communication (with iChat and iSight) can only occur between two Macs (configured with iChat). Is there a software available that will allow an iSight equipped PowerBook to communicate with a Windows platform? I originally thought that an iChat/iSight Mac could communicate with an AOL Aim/PC webcam equipped PC...Any ideas, I have to give a presentation to colleagues in Japan and I'd like to use this technology if possible.
