I remember reading about this years ago, if it could work then it
would be ideal for my situation - maybe for others too. Vadim Epmak's
address is bouncing so I'll ask on the DVB mailing list and see if
anyone else ever got it up and running.

I'm keen on trying it out myself, and have started reading about
porting drivers to 2.6 kernels. Could be an interesting way to learn
more C ;-)
