You don't need to capture all layer 2 (MAC-level) traffic, since traffic is
already directed to one of your interfaces. A transparent proxy needs to be
in your routing path, right?

Only problem is, that instead of forwarding a packet to another host, the
packet should be forwarded to a local process. This would require a patch to
the kernel routing code. Well, if you are patching the kernel anyway, why
not add filtering capabilities?

Seems to me you would end up with something looking very much like
