My package works "out of the box". Install the deb, and flash recognizes the built-in camera on the n800 and n810.

The "wrap" intercepts open to prevent v4l2 devices from being seen, but my version changes the device name in the .so and runs a daemon that sleeps until something reads from the pipe and then pulls v4l2, convertes it, and sends it to its end of the pipe until the far end stops reading. It also loads the video pipe kernel module, all automatically.

There may be a licensing issue since I change a string in the libflashplayer.so browser plugin file so I wouldn't need the wrapper.
