I'd love a multi-ISP solution.  I just assumed that anything involving
more than a single upstream AS across the two links would leave me
having to consider BGP convergence instead of just IGP reconfig.  I
didn't presume that that would likely be something that happened in
seconds.  If there's a fast approach to be had here, I'd love to hear
it.
