And thus you have to hand-craft your connect information. Your client 
has to do an active scan to find the APs for this SSID, doing it when 
you need it, not when it can check other channels in passive scanning 
during 'free time'.

Sigh. 802.11 scanning is really dorky.

OH, hopefully you only have ONE hidden SSID definition active. If you 
have more, then EACH is a separate active scan operation. And on the A 
band, boy does this HURT!
