Dual licensing makes perfect sense, it all depends on why you are licensing 
your software.

I believe there's a discussion somewhere online as to the "whys and

multiple licenses. (Where to find it is left as an exercise to the reader 
because in my quick search I could not locate it after 2 minutes). :)
