We are using radius (and i've used it when i was in an ISP to control more
than 200 million minutes per month) and we are happy with it. There are great
radius servers (radiator in our case) and lots of gateways and equipment
support radius as clients. If you can configure more than one server in your
clients and setup some kind of redundancy on your servers and a database
backend, it works (and you can bill!).

You can keep accounting in a database and text files so you can, before
billing, conciliate both.

I think radius is a good, known and very supported protocol that works ok for
