This confused me a bit because isnt > transport between 2 hosts only 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).

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. > Is the howto below a "real" IPIP version or? I'm not sure what you mean here.
