Ok, so I finally saw the WWDC '06 vid. ANd I really liked the iChat AV enhanced, or on steriods. Well, my question is, does anyone know if one person has Leopard and the other person has lets say, AIM. Will that person with Leopard be able to do all the cool effects? I mean, I kno the person on AIM will still be in their room, with a normal everyday camera and all. But, would I still be able to have the cool background and stuff, and have them see it, or do we both have to have the newest version of iChat?
