You'll have to forgive my vagueness as we're currently 
deploying this in our network, and a lot of the stuff we're 
doing, with vendors and internally, is off-limits for now 
:-).

You're asking the right questions. But as you allude, 
current hardware is problematic, at best, when used to 
extend MPLS into the access. A number of challenges to 
overcome, scale to worry about, price-point, e.t.c.

We're addressing a number of these through architecture and 
vendor interaction. That's all about I can say, really.

We're currently deploying, and hopefully, should have some 
useful operator feedback at your next favorite operator 
meeting (hope we'll both be there). 

Cheers,

Mark.
