Want to dual-home to SBC and Cox? Great. You get IP space from

yet there is ONE route in the global table for the lot of you. SBC and
Cox interconnect and swap packets when someone's local loop goes *poof*.
Flaps within 1.0.0/18 never hit the outside world.
Personally, if I was going to multi-home, I would far prefer that my various transit providers don't cooperate at all, and have sets of peers and/or upstream transit providers that are as different as possible from each others'. The last thing I need are operational procedures which are shared between them.

If all you want is last-mile redundancy, surely you can just attach twice to the same ISP and avoid all the routing complications completely?

I get the feeling that there's a lot of solutions-designing going on in this thread without the benefit of prior problem-stating.
