Conveying the Provided Service
Basic RADIUS does most of this
But some question marks in the corner cases

The most relevant attributes:
Service-Type -- the main attribute, but coarse-grained
NAS-Port-Type -- identifies the physical layer
draft-zorn-port-type-00.txt adds some more
Tunnel-Type and Tunnel-Medium-Type -- identify the tunneling scheme
