Well, there's always the point-point connection variant; using 1394,
ethernet or whatever as high speed serial ports, rather than bus
interfaces. You can use ethernet interfaces and crossover cables, for
example. No hubs or switches, no collisions or anything.
That said, I don't know which is better in terms of hardware and
drivers; 1394 or ethernet... AFAIK, both are essentially high speed
serial bus interfaces, but it might be that 1394 doesn't have
collision detection h/w and stuff like that. Don't know if it's a
real master/slave system on the h/w level. Ethernet is not... With
P-P connections only, it's irrelevant, as long as you can keep any
such logic out of the way.
