You think Apple might introduce some sort of PUSH for this thing? I was thinking they would just need some small background process to watch for incoming push notifications from there servers. I'm sure it would be the same method as over a cellular network but would just identify your device via serial or mac address etc.
It would at least relieve some of the multitasking pains and let you use this thing for IM'ing.
