I think I/O bound is a little harsh - NadaNet can saturate available
memory on a node in about 6 seconds.

Since in a parallel environment the primary use for the network is
message passing, I think 20 nodes doesn't come close to saturation
point. In fact, NadaNets economy of network complexity makes it one of
the most efficient message passing networks around.

And besides if contention became an issue, you could always construct a
NadaSwitch(tm) and move to a star topology, dramatically increasing the
number of potential network nodes :-)
