[nsp] OSPF & Encryption

Hi all,

I've walked into an interesting situation. I am working on a small network
with private point-to-point T1s between sites. We have customers (we're in
the financial industry) that insist that we encrypt our private T1s. We also
want to run OSPF. 

I was going to encrypt the links using IPSec but this breaks OSPF. Cisco's
solution seems to be to use GRE tunnels - something I don't have experience
with. Is there a simpler way? Are there alternatives to IPSec for encrypting
point-to-point links?

Any help will be appreciated.
