That definitely works at first, but my concern there is that in 6 months
we lose the PPPoA guy on PVC 1/520, and a new customer wanting RBE shows
up and gets assigned that PVC.

If I understand correctly, that means I do:
#(config) interface ATM1/0.3 multipoint
#(config-subif) no range qwestdsl3 pvc 1/510 1/605
#(config-subif) range qwestdsl3 pvc 1/510 1/519

i.e. I drop a whole range of PVCs temporarily in order to pull that
one out.  That's going to drop a bunch of customer circuits.  Which
wouldn't be a *major* deal - could do it late at night - except that we
inevitably have a bunch of customers with routers that don't reconnect
and rather than just power cycling, they wait for a day and then call us
in a snit.

Yeah, I'm worried that this will turn out to be impossible when the time
comes.  If the guy I talked to can actually do this I'll see if he minds
me sending you his contact info.  Really, they ought to have a process
in place to handle stuff like this...
