Apart from all the MAC/Mac jokes, I'm wondering what significance (if any) this has for the future of the AIM client on Mac OS X. The last time the official AIM client for Mac was updated was (according to its download
page) on February 18, 2004, i.e. over two years ago. Considering that most people who want to develop an AIM client for the Mac have already done so by using the GAIM core libraries (Adium X being one chief example), what exactly is making an SDK with a small pile of licensing restrictions (you are "not permitted to build Custom Clients that are multi-headed or interoperable with any other IM network" ? Wonder why that is...[/sarcasm]) going to solve?
I appreciate the gesture, but I think a lot more people would benefit if they'd spend their time fixing up the official AIM client for people who don't particularly like iChat or any of the current F/OSS alternatives rather than releasing an SDK that probably won't spur many/any more F/OSS clients because developers will find its license a bit too restrictive.
