I have not seen how to create a library as object-code-only Perl extension. I will take a look, if you have some direction that would be helpful.

I have actually figured out 80% of the file format on my own. Not sure how that might impact me. If I move forward on the NDA I will make sure I have a lawyer look at it. I am not sure they are looking at what I plan as a profitable business venture I just want to provide access to tools for this radio scanner on OSs other then Windows. Also, it looks like fun and a challenge.
