In a perfect world I would like to pass all that traffic, but I can live

It would be operated by me (the provider)

The price is very important, since the alternative is to run few separate
routers, each doing a PPPoE, but that does not scale very well when adding
new networks.

This is as close the the production as I could make it with out over
