I think it is relatively easy to do. There are two places in
src/net_socket.c where you would have to call setsockopt() with the
SO_MARK option: configure_tcp() and setup_vpn_in_socket(). The first one
is run for all incoming and outgoing TCP sockets, the second one sets up
the UDP sockets.

Try it out and see if it really allows you to do the mark-based routing
you want. If it works, you can submit a patch or pull request.
