I said a possibility would be to use IPsec transport mode OVER AN IPIP 
TUNNEL, which is not he same as using transport mode alone (which is 
restricted to host pairs). On the wire, packets generated by either 
approach look identical.

Forget about security for a moment. Set up a virtual topology using IPIP 
tunnels, and make sure it works. *Then* turn on transport-mode IKE over 
the IPIP tunnels to secure it.

I'm not sure what you mean here.
