It only takes a relatively small patch that lets conn-track hash on a skb->foo_mark, and allow that mark to be set on incoming packets based on netdevice or whatever, (before the conn-track lookup is done). This is logically somewhat similar to using multiple routing tables and has been working well for me for several years....
