automatic-heck even manual interface choice per program?

[hackerError]

Hello,
I am a college student and the IT gods of the school have capped every student's uploads and downloads. I have managed to get the IP address of a friend who left the school last semester, and it is valid. I have two ethernet cards on my motherboard, both are configured correctly for internet access, and both are connected to the wall via wall jacks. Heres what I want to do, I would like, and the best solution woudl be, when an app runs that access the internet, I want it to decide which interface is less clogged, and use that for it's business. For example, I run bittorrent, it chooses eth0, and then I can still browse the internet or play online games or otherwise use eth1 for internet access. As it is all internet traffic goes to eth0 no matter what, and It is rather difficult to fileshare and use the internet at the same time.
