Video compression has become a lot better today ;)
The case where you plug the USB is very impressive. I didn't know that
this can work *at all*.
Side-topic: I've seen there was a project called vjack / video jack. There
are other programs which refer to vjack, but I can't find any source for
vjack. It seems like an abandoned project. If anybody has more information
or even an archived source tarball, I'd be interested to get a handle on
it to see how it was envisioned.
