By default, Telus in western Canada has deployed ethernet based DSL for
wholesale, although PPPoE is available. Its own customers are ethernet
based wth DHCP service.

Some of the ISPs have chosen PPPoE since it makes it easier to do usage
accounting at the router (since packets are already asscoated with the
PPPoE session account).

The difference is that Telus had purchased/developed software that made
it easy to change the PVC to point a user to one ISP or the other, so
changing ISPs is relatively painless. Bell Canada decided to abandon
etyernet based DSL and go PPPoE because it didn't want to develop that
software.

Bell is deploying PPPoE for its FTTH (which is not *yet) available to
wholesalers, something I am hoping to help change in the coming months)

However, the australian NBN model is far superior because it enables far
more flexibility such as multicasting etc. PPPoE is useless overhead if
you have the right management tools to point a customer to his ISP. (and
it also means that the wholesale infrastructure can be switch based
intead of router based).
