In what way will the way the pop under change in the way it is presented? It really doesn't matter how it is presented, if it pops up in the "users" space it is going to be hated by most people. Media center PC's, presentations, people doing real work will always find it a huge annoyance if it uses the user program space (the desktop) in any fashion short of checking that the PC has been idle for at least a couple of hours and that no media types are playing.
