Aaron,
With as large as this is getting, you really want to do this right from
the start. Has the company given any thought to disaster recovery? With a
thousand remote sites, this can't be a small company, so a circuit loss at
the main site could be horrific. Backup PVCs to another location are the
norm for a network of this size. But it's nothing that OSPF can't handle.
Just design it right, and maybe you'll get a big bonus for a good job!
