On the subject of multihoming

I'm working on a small experiment which utilizes multiple outbound links 
(in the experiments case multiple consumer 3G connections [to 2 Sprint/2 
Verizon/1 AT&T], Time Warner Cable Modem and an SBC Global DSL connection.

What is the best way to do outbound traffic engineering? I would like to 
be able to determine the best path possible and send traffic out the 
appropriate link.

Could this be done with a copy of the BGP tables?

Obviously as they are consumer connections, I wouldn't get a BGP feed so 
would need to download a copy, which has the risk of stale data. Perhaps 
some sort of multihop BGP setup?

I have done some research and found a lot of references to small site 
multihoming without BGP for link redundancy but not for traffic 
engineering.


Thanks.

Charles
