What source code was being talked about? I'm not talking about
anything userland, and my driver is just turning on a hardware
feature, I can't imagine HP having anything to do with it, but I
double check internally.

Also, there is the ptpd project on sourceforge, that even uses
a BSD rather than GPL license, should be easy to use, but
I'm new to this so its possible I'm missing something? I'm
basically tasked with adding driver support, what happens
to actually use it is another matter :)
