well, depending on how you look at it, you can't. Most protocols require a tcp connection (2 way communication). So you have to fool them. If you bond the 2 interfaces together and use iptables to block all traffic in one direction on each interface it might work.

2 A.M. in the morning and i might not be thinking straight.

Now that i've had some sleep. I'm pretty confident that you can't do what you are trying to do. You can however, set certain traffic to each ISP
