Eh - no - most setups deal with some 10's of messages a second at the very
least; esp. when the RTT is short. With longer round trip times and real
long distatn conenctions you'd front it with apache anyway - so that
offloading of the stack would again give you 10-100's of connectioons even
on the most modest hardware (say a 450Mhz Apple iBook / 256Mb / MacOS X).
