How many clients?

[Kristian Hoffmann]

If you want some random (probably useless) statistics, we have one AP
running the hostap driver with XI-626 cards that have 70 stations spanned
across two radios.  The uplink is two T1s connected via a Sangoma S517
dual port T1 interface.  The AP is also doing traffic shaping with HTB
(one class per station).  It hasn't blown up yet. ;-)
