Radius and MAC Address Access Control

Hi Nathan, guys.
I have a setup like that today except I use pptp vpn tunnels for my users. The vpn daemon (poptop) talks to freeradius server which against gets user info from MySQL database.
I use dialup_admin to be able to easly add new users.
Everything works great except for one thing.
The users (companies) are unable to create their own VPN tunnels (i.e IPsec) to other places.
It's impossible to tunnel IPsec inside of pptp vpn tunnels.
So maybe running plain PPPoE could solve that problem.
Then I could use WPA for traffic encryption.
Does that sound logical?
Nathan. Do you do controll the bandtwith of your users too ?
I need some kind of system that will make it possible to give different bandwith to different users.
I though I could set up DUMMYNET with bw restrictions for different subnets with a subnet mask like /16 or similar.
Then give static IP's to my users depending on what bw they are allowed to use. But this approach does not seem to be very flexible.
Is there a way to make radius do bandwith restrictions or run commands against an external application?
