ok, let it be out-of -tree driver, this is also good as I do not have
to adapt the driver to each new kernel, but I want to argue alittle
about Inclusion of the driver into upstream kernel.

 Main reason for inclusion to the kernel is ease of use, as I
understand installing the out-of-tree driver for some kernel needs
downloading of the whole v4l-dvb tree(am I right?).

 Loopback gives one opportunities to do many fun things with video
streams and when it needs just one step to begin using it chances that
someone will do something useful with the driver are higher.

 Awareness that there is such thing as loopback is also. If the driver
is in upstream tree - more people will see it and more chances that
more people will participate in loopback getiing better.

 vivi is an upstream driver :-)
