[e2e] SLOW TCP flashmob meeting

[George Michaelson]

I had a very good message on SLOW TCP but unfortunately, its too big and will
take too long to arrive, for your flashmob.

-George

PS, would it not be more in the spirit of E2E to propose that the flashmob use 
self-chosen <random> algorithm, with the aim of achieving the maximal goodput of
inter-person-arrival-time, such that no more than one person is actually at the
flashmob meeting place at any one point in time?
