I guess I'm missing something here.  How would this compare to going
with a switch that has a large number of ports with a really fast
backplane?  Like say a Foundry BigIron 4000, or some such.  Is this a
just a cost vs. performance issue?  Can these switches be wired in such
a way to out perform a fast backplane?
