Multi-gigabit edge devices as CPE

Is it a necessity to terminate the layer 3 at the edge? You could get a
10Gbps switch and move it all back to a central location where you have
your high end routers. It would then be terminated as a VLAN and be a
router on a stick kind of topology. Could be a cheaper way to do it without
taking MPLS all the way out to the edge.
As Tim said above, I too was thinking about the Juniper ACX. The 5048/5096
model could suit your needs. They are primarily designed as layer 1(TDM)/2
backhaul devices and i'm not sure they can do a full table. They do have
full JunOS MPLS features. Could be a way to use MPLS-TE to move the layer 2
back to a core location and terminate later 3 there. Would give you some
flexibility over just doing ethernet stuff as I mentioned in the first
