You should join the list and the quit when you are done.  Otherwise,
like with this email I get multiple copies of it.

I am in a chassis.  I need a way to do interface card communication.
Even if those cards are exposed to the outside world.

Yep.

Right. That works too.  But what I did was about 10 lines of code.  And
I refined it a bit better I believe.  That way packets destined for "my"
internal network got out the appropriate interface.  The rest go on
their merry way to the loopback world.
