Well I may have jumped to conclusions about what was meant by
"rendering"... You can't just "view" the remote system's desktop and
see the video if an overlay, or see it at 25-30FPS if it isn't an
overlay, that is too great a datarate.  Even if the video playing on
the "server" system was compressed, it isn't being transferred over
the LAN as such through the remote control program.

If you instead used the remote-control program only for initiating the
video steam, changing channels and such, then it's possible.

Using a steaming, moderate to high compression codec like DIVX, a
common 100Mb LAN would be more than fast enough.  It's not out of the
question to do Divx, the question is how, if it's possible, to set it
up to stream.   

I had an Athlon XP220 doing realtime Divx capture at 640x480 w/MP3
audio, didn't try to underclock it to find the minimum perforomance
level necessary, but that's a suggestion for a minimal performance
target if you wanted streaming Divx, if you can find a way to stream
it.  It might be good to assume there would be additional performance
needed for the streaming though.

You will probably need to do this backwards, find the streaming
solution you want to use and THEN determine what it's compatible with,
and THEN determine the system specs needed to do it.

Why not just put a tuner card in the remote system(s)?
