The simplest thing would be to insert a second network card that
is dedicated for realtime communication with point to point
connections. You simply disallow stadard linux to load the standard driver
module, then you can do with the card what you like, especialy
programming an rt-linuxdriver.
If you connect two ethernet cards with tpi-interface directly with
a crossover-cable and use error correction coding for the
data packet to send, then it should be possible to have
realtime-aware communication.

Some weeks ago, i read something about realtime-ethernet
for rtlinux at www.zentropics.com, but i can't find the
article any more :-(
