The best conference WiFi experience I had ever with was the
SIGCOMM'07 conference room in Kyoto
International Conference Center in Kyoto, Japan. It showed
nearly no service interruption for my laptop. It might be
interesting to learn from our Japanese colleagues how they managed
to make it happen.

The NYC article hints at the fact that the limit may be hotel fiber, rather than wireless, in some cases. We seem to have more experience with dimensioning those than other organizations.

In the end, this technology will not scale without bonds if we're talking about n-thousand people sitting in a plenary hall, but there are obviously a lot that can be done with a distribution of multiple lower-powered (configured as such) units that don't use overlapping channels, use of various 802.11 flavors (a, n, etc) and more SSIDs, all in the name of load sharing. While there may not be a document, and I agree that it would be useful to have one, there is certainly a collective body of knowledge on this topic (including a "never again use base stations from xxxx..").
