How many clients?

So, HostAP seems to be limited to somewhere around 15 STAs
(client devices). This makes me think of a question. Why can an
Orinoco (Proxim) 2500 AP handle hundreds of users, and HostAP can only
handle 15? Again, I understand that 11Mbit/sec divided by 100 users is
only 112.64Kbps, but you will never see 100 _simultaneously_ active
Another thing I was looking at was the code for the HostAPd
system. Would it not be faster, and more efficient to define a
large(ish) buffer for functions like `handle_read()` to drop data into
instead of defining variables every time those functions are called?
Then, you would only have to pass the address in the buffer between
functinons. Anyway, just a thought.

For more users, I'd wager, than a nominal 11Mbits/sec link could happily
