I think it's a great idea! I also think you are on the right path with using a barebones environment; I use Linux, but it's not right for the purpose.
The biggest market I see for something like this is games or displaying some sort of video. It seems like it is getting harder and harder to find something that Java/Flash can do that HTML5/Javascript can't but they still have their uses. For Flash it's RTMPS for encrypted video. For Java it's ease of development.
I'm so intrigued because it seems it seems like an awesome way to do some browser fuzzing :D
