Two variables: users per access point and access points in the same
place: 

802.11a, G and B access points all have different capacity.
Realistically, with .b the speed will drop to zero before the ceiling on
users is hit. Dunno about the other two, but there's probably a hard
limit. 

You can theoretically have more than one access point in the same place:
up to three (if they're tuned properly) with 802.11b and theoretically
over 20 with 802.11a. This is because 802.11a runs in the 5GHz band
where (in Europe and the USA) there's up to 605MHz of spectrum to play
with, versus 83.5MHz in the 2.4GHz band used by .b and .g. 

The catch is that for wide area coverage you need overlapping access
points, sort of like a cell repeat pattern.

what's the limit of the number of concurrent users of a hot-spot?
