I have for quite som time now been dreaming of iChat with PUSH-tech.. I remember a lot of others hoping for the same thing, but it now seems that everyone has settled for a stand-alone for OSX.. I hope that negotiations with Apple, if not already in progress, will start soon.. I am sorry to say that I am just not satisfied with the Skype-app.. It's always been a bit to windowish for my likings and after seeing the beta for Mac I haven't exactly changed my view on that.. The tech however is great and implementing it to iChat would create a monster-app!
Please.. I beg of you.. Consider it.. It would meen a great deal to Mac-users around the world and I'm sure it could only give you even more advantages on the whole IP-tele-/IM-/conferencing-field.. Mac-users are in my experience generally people with great buying-abilities and quite an interest in up-coming technology..
