Can you elaborate on why you are choosing this approach? Why not ethernet?
Latency and throughput are not very good with these cables, relative to using
100BaseT (or gigabit, if you have that many machines) ethernet.

Of course.
I suggest that you look at the usbnet driver included in the current -ac
patches. You can easily include it in another (2.4) kernel if you don't want
to use the -ac tree.
It provides pseudo ethernet interfaces at each end, and you can use all normal
kernel networking with it.
