Why do it through Radius? My idea is this:

Make one filter, either in the Portmaster(s) or through a ChoiceNet server
which has something like this:

permit assigned_ip/32 0.0.0.0/0
deny

So it would only let packets coming from the ip assigned to the user get
out, no fakes. Do the opposite for the incoming filter too. I wish there
was an automatic way to do this..
