Absolutely, and it still works great for that purpose.

However, given a provider backbone with Ethernet being the underlying
technology, I don't see why anybody would want to use PPP on top of
Ethernet instead of just plain Ethernet. After all we're *not* talking
about DSL or dialup here, there's no need to authenticate users etc.
