If your provider does Unicast RPF strict mode, which I hope _all_
end user and small business connections default to doing this won't
work.  The traffic has to be policy routed out based on the source
IP.

Having the host stack do that is an acceptable solution (your dual
router model) I think, but I don't know of a single one that does
that today.
