Okay, so if I need to touch every computer anyway there is no real 
advantage to getting a commercial certificate.

My main purpose is for logging of what AP is being used by what device 
and when. There are several laptops running Windows 7 and/or 8 which are 
not on a domain so group policies are not an option. There are also a 
number of BlackBerry smartphones which I can control from the management 
server. For those I should be able to push out a certificate and send 
the updated WiFi configuration to them automatically. The AP's are 
various D-Link routers running DD-WRT. I put together a test setup, but 
I had to jump through some hoops to get a Windows 7 machine to connect, 
but that was because of the cert not being recognized.

I guess my next step is to generate a CA cert etc.

Nope, not eduroam.
