To run this, you need to have JAVA on your Ipaq. You can run a JAVA emulator on a 'native' IPAQ with WinCE or replace it with Linux and Java or run a native Java environment. The site below gives all kinds of details about it.

I kindof like the idea of the emulator on WinCE. That way I can still run my card's native diagnostic/site survey tools (Cisco and Orinoco), NS Mini when it comes out or the wireless sniffer.

I'm still not sure if there are drivers to put either of my cards into promiscuous mode on an Ipaq but this certainly seems like a pretty cool addition to a sumbling setup.
