It is even not an optimization, but it is required to provide
internal routing consistency. I see, it is bad news for you.

Now good news :-) There is a hole (read, bug) in 2.1: if you make
SO_BINDTODEVICE to your PtP device, packet will go through
this device.

And bad news again: these packets will be dropped
on another end of link, because IP considers them
as the the most weird spoofing attempt. This check can be
turned off by commenting several lines in kernel.
If you really need it, I can supply patch.
