I'm thinking that, if you push L3 termination all the way out to the last access node (FTTN DSLAM being the obvious one here), you may then lack a decent way to haul pure Ethernet back to their head-end. If your L3 termination also supports MPLS, or Q-in-Q, you're probably fine. The latter might negate the potential advantages of distributed L3 from a routing POV by forcing you to again run STP or similar. If you're doing L3 termination a bit more centralized, even if not with big behemoths on a "one per super-metro" basis, this may not be a problem at all. HFC and FTTx PONs might end up being like that inherently just because of the nature of the plant and tech that runs on it.
My assumption is that you'd be running full IP/MPLS all the way into the Access. In that case, what I'm saying is that you can run EoMPLS to deliver the service. Mark.
