PulseAudio and v4l2 for Flash

I just tried out PulseAudio yesterday and found it a rather enjoyable experience. The only thing that didn't work out of the box turned out to be Adobe Flash. I soon found libflashsupport that I think is rather interesting. In addition to how it's used there, I'm guessing it should be easy to whip out support for v4l2, which would help if you have a modern laptop and want to use the uvcvideo-driver.
