Cistron Telecom in .NL built a network exactly like that by placing
the BBRASes (redback) close to the DSLAM, then encapsulating the
traffic for each wholesale customer into a MPLS VPN using Juniper boxes.

Unfortunately due to the bad investment climate and problems
with (de-)regulation and the local monopolist Cistron Telecom
doesn't exist anymore, and Cistron Internet is now a client
of another wholesaler that indeed delivers DSL circuits over
ATM to use in one central location (for the entire country!)

Looking back I am still convinced we had it right but we
were probably just way ahead of our time, alas.
