There are a variety of layer 2 solutions for this problem. One simple
solution: Get Cogent to provide you two "sessions" via link layer
identifiers - FR encaps with separate DLCI on POS or two separate
VLANs on Ethernet. Then use the L2 solution of your choice - GRE
tunnel, Martini, whatever.
I also sort of like "get the customer their own connection to Cogent".
