Note that there's a lot more to this kind of solution than “not badly
overbuffered”. In particular, you have automated systems for channel
assignment, for biasing people onto 5 GHz (which has 10x the number of
nonoverlapping channels) and for forcing people to be load-balanced between
the different APs. All of this helps in high-density.

A lot of what's problematic in crowded areas is actually control traffic,
not data traffic, especially since it is sent on the lowest basic rate.
(So, well, one thing you do is to set 11Mbit or whatever as the lowest basic
rate instead of 1Mbit...)
