How do you AB through a proxy?

This is a question that's been bugging me... I don't see the point in multiple accounts unless I can AB on them, except the only way that'll work at all is if I run each through a different proxy.

Any way of doing this? Thanks.

 

If the program has proxy support, you can enter a proxy into that and it should work

 

Thanks.

Is there a way to route outgoing TCP requests through a proxy? Seems like it must be possible, but I haven't a clue how.
