Since the original question was how to do it without IPSec on IOS. How about putting a PC running OpenBSD with IPSec behind each router? Make the IPSec tunnel between the two PC's. The software is free and a PC can be cheap. What would be needed, a 233MHz?

Follow this up with #2 for more security. 2) Very restrictive access lists permitting only the other peer and denying everything else (is this practical in an Internet usage scenario?) Other than encryption and hashing algorithms, there's not much else (I think!)
