That's exactly what I wanted to implement. Nice that I don't have to do
it, but can instead concentrate on an alternative output-plugin, that can
be used together with sdl/x11 an my epia-m-board.

If you implement multicast, please still offer unicast-mode.
Do you want to stream pes or the raw ts-packets? I looked for a way to
stream the ts-packets, but there seems to be no way to do this (klaus
said, that there might come something in 1.3). This would require less
cpu-power at the central vdr-server.

My thoughts on the client for vdr:
Implement it as a plugin that uses the cDevice-class to provide input to
vdr like a nova-card (incl. tuning and so on). The plugin would translate
the tuning commands from vdr and send them to the central vdr-server. It
should look like a normal vdr-machine with a real dvb-card.
Perhaps we could work together on the client side?

That's on my TODO and I just bought 2 more nova-cards on ebay, so i have
enough test-equipement ;-)
