Could you run a ping script to the given monitored IPs (or use something
like Nagios) and then run a script to update the routing configuration
on a router that can take external commands easily? That's the approach
I would take from a cost to performance standpoint, unless I
misunderstand what you are trying to do. I did something similar to
that years ago with a cheap Linksys router (but I opened and closed
ports within a LAN rather than modifying the route between two WANS in
that case) to do primitive failover. It worked perfectly.
