It's a matter of economies of scale. If everyone has to light their own fiber, you haven't saved that much. If the fiber is lit, at L2, and charged back on a cost-recovery basis, then there are tremendous economies of scale. The examples that come to mind are campus and corporate networks.
The problem is rolling out new services.We have a big share of home connections here in Sweden based on L2/L3 muni. "None" of them have IPv6 and when you ask them, there is very little response.
Of course there are a lot of different models here, everything from the guys who do L3 (you route a /21 or something to them) to L2 (they do all antispoofing stuff, you get plain L3 interface) to QinQ style handoff (increases ISP cost because QinQ capable router is more expensive).
About device requirements mentioned earlier in the thread, just want to provide this link:
<http://secureenduserconnection.se/2012/03/23/new-sec-access-certification/>These guys "certify" vendors to have all the proper antispoofing/anti-MiTM/etc functonality to deliver a proper ETTH service.
The requirements document is publically available and a worthwhile read if anyone is new to the ETTH business with active ethernet.
