With a protocol to distribute which prefixes (with weighting) are
viable, a end node could just select a appropritate source address
out of several provider assigned ones and use source address routing
to find a appropropiate exit path which doesn't break BCP 38. This
is as good as the NAT solutions for small-site multi-homing today.
