It appears that kismet requires either someone to walk around the facility while running the program or that you have you have it installed on machines all over your site. Neither of those options interest me as a long term solution to rogue AP monitoring.
You could setup a laptop, a GPS with a data cable, NetStumbler[free], and a 8dbi 2.5ghz <802.11b> antenna and pickup everything clearly for a half a mile without walking around. I've just acquired this setup myself. Google on "war driving +F150" and you'll see a setup to help for < $55
If you are driving then you might want to build something using the DashPC http://www.dashpc.com/ but for walking around it's even easier if you use a Linux-based PDA like the Sharp Zaurus which runs kismet. --Michael Dillon
