What routers have you decided to use at the edge ?

at your branch offices, are you terminating the ipsec lan-lan tunnel on a firewall or a the router? for your vpn connection, you could use gre over ipsec to pass your routing protocol. your dll is always up, so you could also enable routing on that interface. you'd just have to tune your routing protocol to prefer routes from the primary link, in your case the vpn link.
