Look in to the "--next-hop" "ip route" command option. I think you will find what you are looking for in the fact that you can have multiple next hops. Something to keep in mind is that if you are NATing each ISP connection, you can not have a stream migrate from one ISP to another b/c you will break connection state on your end, or even if your end could handle it, the server you are connecting to would flip out. From the server's point of view, it would be talking to Bob and Bob would stop mid sentence and Tom would start where Bob left of with out the ability to correlate what Bob and Tom were saying in to one coherent stream.
