What if we added tap(4) support to launchd? Would that satisfy most of
your needs?
If you want something running all the time, just set OnDemand to false
in your launchd configuration file.

For this reason it can't really just start running when a connection
is made to
some specific IP address, since it won't be listening to any
specific port.
I am open to suitable approaches for allowing this to start running
when the system
starts. I haven't really played much with launchd and I was
following what I knew
worked. How would I present this to launchd?

Depends. In a server environment, I'd want the service available and
ready to take client connections immediately - without any startup
overhead - especially if it needs to perform lengthy initialisation.
You can't generalize like that, however. You might want SOME
services to start immediately (in which case, the RunAtLoad launchd
plist item is probably your friend) but ALL services? No way.
That's just wasteful, and unless you make a habit of putting 4GB
(for now!) of memory in every machine you own, probably going to
have a noticeable performance impact as other things fight for the
memory that's being taken up by all those services just lying
around doing their nails and watching daytime TV.
Sorry, but the "server environment" classification hardly
guarantees that each and every service being provided by the server
needs to be running all the time, particularly in SOHO
configurations where one box serves potentially dozens of needs "in
theory" but, in practice, finds many of those needs to be
occasional usage scenarios at best.
