ISP SETUP

I use ROS for PPPoE customers Auth back to our RADIUS server. I want to be able to give an authenticated user an Authorisation of an IP/Bandwidth limits/etc and are able to access the WWW

When a user has no credit, I want to be able to send them to the walled garden for payment etc

I also do not want some websites to count as data usage for d user.

Finally, I am looking at d routeros reporting d data and validity time the user has left (accounting, Cisco implements this bit on a BRAS as Qt, Qv)

Is this possible using standard PPPoE and if so can you please point me in the right direction

Any help is great.. thanks in advance
