Well, that's not too far removed from the plugged-in laptop with the
wireless still active. Toss-up which one wins default route.
What would you "like" it to do? BGP feeds from both (likely not
happening)? Defaults from both? Or you just want active/passive failover?
The real-world case for host routing (IMHO) is a server with a public
interface, an administrative interface, and possibly a third path for
data backups (maybe four if it's VMware/VMotion too). Unless the
non-public interfaces are flat subnets, you need some statics (today).
It can be a challenge to get SysAdmins in a co-operative mindset to
route that correctly (and repetitively if you have a server farm).
I would be walking the fence on the virtues of automatic route discovery
in that case versus the security of static routes/configurations.
But home use from a host perspective?
