Big Temporary Networks (Dreamforce)

Anyone from nanog currently at the wheel of the conference network at
Dreamforce in San Francisco (nearly 70000 attendees)?
It appears that all of the suggestions posted to this nanog thread so far
were thoroughly ignored. Conference WiFi is effectively unusable, despite
the very visible, expensive-looking enterprisey APs on temporary stands
sprinkled throughout the conference.
As far as I can tell, they're doing NAT, using a /16 per AP (which could
amount to 5,000 or more devices in one broadcast domain depending on the
location!), and are using what appear to be omnidirectional antennas at
full blast power instead of zoning with tight directionals.
Wifi is nearly unusable; even Sprint's crappy 3G coverage is faster and
more reliable inside the conference halls..
