I finished reading the paper today, finally, on the train from mantes la
jolie into Paris....

Aside from admiration for the scope and breadth of the analysis
(particuarly chapter 8 forward - I'm rather dubious about most
classification teniques)...

My principal question on all that work... All the models/sims were over
ethernet and assumed fairly high bandwidth connectivity.

I would really like to take a recent model showing 'fairness' of a
network protocol such as LEDBAT, and apply it to a set of wireless
connections that exhibiting the kinds of behaviors we've been seeing
(exorbitant buffering and retries)  The results should be... interesting.

Perhaps the models used here - or the real implementation(s) - can be
fed buffer sizes in excess of 1064, and delays in excess of 2 seconds
... over fairly long paths.
