Sorry for not responding earlier. I think this smart-gw is
very useful. I don't have cycles to check it right now.

One tunnel doesn't provide multi-path transport protocols. And cannot
support seamless handover. For this, we need source address based routing,
for outgoing tunnel selection. It's a next step.
I proposed BRDP based routing, where instead of a default route,
packets are routed to a GW that "owns the source address prefix".
This is proposed for IPv6 / Autoconf and more a long term solution.
I think BRDP-based-routing can be used with the smart-gw-tunnels.
It solves ingress filter problems.
