With questions like this it seems everyone has an answer, but 
everyone's answer is different. I, for one, have consciously decided to 
never use the GPL on any of the software I release. I use the ZPL.

Fortunately I have not been in the reverse situation where I had to do 
customer work developing software on top of/with GPL software. At that 
point I'd be confused, too...
