How about lots of GRE tunnels? :-)
I've done that with a few connections - mostly connecting to Cisco routers to pass multicast streams. I'm not sure how it would scale up in terms of the interface numbers and managing routes but it should work.
What was the network environment like that the tunnels went over?
Some over the internet, some private, but always with fixed src/dest addresses and nothing going over them that couldn't have run unencrypted over the internet.
