Most of the OSS radius servers that I have seen allow you to run an app
when the user attempts to authenticate. (I have only done this with
cistron, though I know gnu-radius and freeradius both support it.) You can
use that app to add the MAC to the DB. The "fun" part is getting the MAC
from the user. If you can do that, then you're good to go.
