Packaged version?

Does anyone feel up to knocking up a packaged version of this which starts tcpcryptd and adds the relevant firewall rules on boot? I could probably just about hack it into my startup scripts myself, but I always feel bad doing it (like I'm bound to break something later), and making a proper package always intimidates me...

Admittedly it is a bit pointless right now, but I would quite like to try using this for a while and see if I encounter any breakage or noticeable overhead. I haven't been an early adopter for ages, it might be my turn to suffer for the greater good. :-)
