I recently found my old X50V which I hadnt used in a long time (used to be mobile a lot of the time, now mostly at desks). I wondered what i could do with it and I thought of possibly a nice low power web server ... and sure enough there seems to be a lot of options for web server apps that will run on a Pocket Pc (I got mine up to WM5 A02, a big improvement) ...
But at about the same time as this crossed my mind I wanted to make my wireless network fully 802.11n and attaching a 802.11b would not be good for that (see
SmallNetBuilder - Add, Don't Replace When Upgrading to 802.11n wireless network performance is atrocious in mixed environments and WPA2 seems to have the lowest overhead) ...
So, brainwave time .... get a CF ethernet jobbie, get web server AND radius server (needed for WPA2) on the Axim and Roberts your relative. Except I cant find a radius server that will run on any type of Windows Mobile device

. Anyone know how I might get a working radius server going?
