To make things even more interesting... While discussing this with a few different vendors I decided that this particular solution is smoke-and-mirrors, at least in our area. We'd have to buy new point-to-point circuits that all point to a _single_ POP.
MPLS isn't even needed in this case because every location would be hitting the same POP! Unless, of course, they have a whole bunch of routers at the POP but then we're really using MPLS to get from one side of the room to the other. We'd be better off simply buying a couple of frame DS3 circuits for our hub and repointing all the branch PVCs to those circuits. Cheaper and we accomplish the same thing without using another vendor and without buying a whole bunch of new circuits. In fact, one vendor that I asked about this proposed this very solution, except he was suggesting we use their facilities. They offered to set up a couple of routers exclusively for our company to connect to. Again, we don't really accomplish much with that solution since we can do that at our own facility if we want to.
