Yes, RF contention, but what Scott is pointing out is that due to
various implementation glitches, it's a lot worse than any theoretical
anything.

I think he's saying "be pessimistic", dodgy wireless drivers, stupidly
implemented programs will spew crap in the RF and mess things up :-)

See the mention of a bogus ad-hoc network in the 2007 report. I've
seen quite a few other mishaps where a single misbehaving node messes
it all up.

Yep, that's the other good point.

I am with the Pycon guys that the all the multi-antenna enterprisey
APs that I've seen don't deliver. Lots of carefully configured
mid-range APs do better.
