Now I know no one knows exactly how this will work until the software comes out, and I'm usually against these kinds of threads, but I'm kind of curious as to how programs like AIM and Twitterrific are going to work if there aren't "true" background processes. Say on AIM I am logged in, and I leave the program, will it stay connected, and if I receive any IMs, they will all show up when I open the program again? Also for Twitteriffic, any new tweets that come through will show upon opening the app again.
