Glennzo,
On the subject of wireless security, I recently found a decent solution/alternative to the crowbar method of turning off the router radio .[ That's what I used to do also] WPA2 Enterprise and radius without hours of set-up/conifg time.
About a week or so ago I took a old pIII server{single core 1.7pIII 512ram} that was collecting dust and installed CIITIX-WIFI on it. It took all of about 10 minutes to install and not much more than that to get WPA2 Enterprise/Radius working with a Cisco type router running dd-wrt.
CIITIX_WIFI is a Debian based distro designed as a turn-key install. It has worked well for me for the past week or so. The distro has a few things you might want to "fix" after a install, like setting-up a firewall, secure ssh, and updating any security fixes through apt-get.

I have read that it works fine from a VM so no real need to run more hardware.
