Actually, not difficult but time-consuming to develop since it would require an entirely new architecture that's different than the FLV version. I'd really like to see where H.264 goes with FLV support. And yes, now I understand the root of your question.
Truth is though, I may very well make a dedicated QuickTime viewer like the FLV version once some other new major features are out the door. There are some really cool things coming up! =)
