I also agree with another commenter that at some point Apple might open up task specific threads such as an AIM listener. Those would be required to be vetted by Apple before release. I would presume those will run as child processes to a babysitter task that could throttle them as needed. To my knowledge, such a thing does not exist in Mac OS X, and coupled with the huge effort to get the SDK, wasn't even considered. Unless AIM currently supports some flavor of message queuing, I'm not sure what would happen with the messages when the AIM client isn't running. Currently, AIM doesn't allow queuing messages while users are offline. Very well written.
