I would quite seriously suggest that simply putting everything on a
100Mpbs ethernet switch will probably do you fine to begin with. If
you discover that you are even *capable* of maxing that out, you can
start to look at doing things like installing two ethernet cards per
machine and using two switches, and deciding programmatically which of 
the two to send data down.
