It's the summer before I go to college and I have little to do when I'm not working. I was wondering about something that has irritated me and many other iChat users for a very long time: MSN A/V support. Mercury Messenger has it. Several other apps do, too. I was wondering how much Objective-C I would have to learn to be able to take that code from a third-party app and write it into iChat for MSN Jabber A/V support. Time... is not an issue. I'm going to college for computer science, so I will probably learn everything that I will need to find out how to do in due time... I'd just like to get started on my own. Can someone point me in a direction leading towards understanding the code that I need to understand?
