I steer clear of DJB's software.  He used to offer his software under
a license that forbid modification, and I am leery of "public domain"
software, <http://www.linuxjournal.com/article/6225>.

We use 3rd-party software under GPL.  Quagga, for example, is GPL
software.  WiFiDog, too.  Most of our original code is BSD, and all of
the code we have started from scratch is BSD.

We avoid mixtures of GPL & BSD.  For example, no GPL code in the BSD
kernel.

I think udhcp will work fine for us.  We just need to finish porting it,
and then we need to make it work with our scripts.
