Hi, i've been using iChat AV for as long as it's been out, for video conferencing. I currently live in Hong Kong and my family is back in Boston, and we chat with no problems. obviously, we both use Mac OS X, with iChat AV, and iSight... all mac... BUT. my sister is a non Mac user... (don't ask why) and we would like to chat. in fact there must be dozens of people i know who use AIM 5.5. so is there really a solution? anyone with success stories, because i'm one lost cat here. Thanks MacRumors forum.
