Tunneling GRE within IPsec would work, but I would only suggest it if
you are trying to tunnel non-IP packets.  If you're just trying to
tunnel IP packets, then just use IPsec's tunnel-mode and be done with
it.

Not if existing dynamic routing protocols are required inside the virtual topology. See draft-touch-ipsec. (Details in my earlier reply.)
