Encap/decap is always costly unless mitigated by special hardware (which 
of course costs money, but in volume can be low). ISPs are doing PPPoE 
because of other reasons, not because it's easy on the forwarding plane. 
Most of the motivation I've been seeing revolves around the same reasons 
enterprise want DHCPv6 IA_NA "that's what we've 'always' been doing and we 
have the systems to support it".

I prefer IPoE, but that seems to be common here in the nordics, but the 
rest of the world seems to have converged around PPPoE.
