Use IP with the linux kernel. IP is not able to transfer data in realtime,
so we don't need IP in the rtlinux kernel (realtime level).

I think it is very important to have the possibility to transfer realtime
data with rtlinux over a network to other rtlinux systems, or what is much
more important to other network nodes like sensor, ionodes ...

To do this you need:
- a realtime network hardware (e.g. ARCNET, ...)
- a realtime software protocol (not IP) or simply raw access.
- a rtlinux network driver for this network hardware.

Has anybody written a rtlinux driver, and for what kind of hardware?

I've talked to Claus Schroeter at the Linux congress '98. He plans to
port his CAN driver to rtlinux level. When i've some time, i would like
to write an ARCNET network driver for rtlinux.
