The thing is we already know that large buffers help greatly.
Seeing how fast one can push a box with big buffers might be
cool, but is it accomplishing anything?  As you demonstrated,
anyone who needs that speed here and now can get a private line
and use a stock *ix install.  Done/done.

How about other models?  Limited server buffers (it's nice to
handle more than 25 simultaneous streams), random-bandwidth
clients, congestion, jitter... how were those treated?  Have
these been explored?

If there's going to be research, let's see some TCP stack tuning
and the results.  Investigating other protocols would be nice;
perhaps the scope of the contest should be changed.  The level of
"research" in unleashing bone-stock equipment is more appropriate
for an undergrad paper than a news release.
