To start, this is more of a list question that a dev question.

I just spent half an hour trying to figure out what it is, and how it works. 
I failed.  We will need a lot more information and what you are needing 
here.  However, on thing I noticed was your comment about SSH.  There is an 
exec.php that has a limited command line.  There are also some custom images 
with SSH.  However, we do not use rc files...

Yes but...  How do you do both a static and DHCP?

A lot more information is needed here.
