sound relatively clear. I'm not really getting whether you distribute
source or binaries. In general providing that licenses in some "about"
dialog or referring to it from your README or whatever should be fine.
If you can describe in more detail I assume that group@qhp.net (I'm no
member there can't speak for them) will help you ..,. but mind if you
really go into legal issues: Ask two lawyers and you receive three
answers. ;-)
