offtopic question about high density wifi

I think I recall that brief testing with a bunch of consumer access
points at OLPC showed that this number was usually above 15 clients
and below 30 clients, per AP, at 54Mbps.

For hosting hundreds of devices, you should look into getting many
access points that each have three omni-directional antennas working
on non-overlapping channels.  The PyCon wifi team does a write-up
about their setup each year, which seems to contain more information
than anyone could need:
