I'm not talking about VLANs for the 3GPP case. In the 3GPP case you have a bunch of point to point interfaces (tunnels / PDP contexts / PDNs; one or more per user) that each have their own network segment (a /64). Per-user configuration is achieved simply by saying "the user on tunnel X gets an RA with prefix Y". This is how IPv6 on mobile networks works today. If you want more specific routes, you can easily include those in the RA, because as Jouni says, this is tied into AAA already.
