So it looks like DOCSIS cable has a great solution with IPDR, but what
about DSL, GPON, and regular Ethernet networks?

It was mentioned that DSL uses radius, but most new DSL systems no longer
use PPPoE, so I don't believe radius is a viable option.

What about Wifi Access Points? What would be the best way to track usage
across these devices?
