Open Source License Question

Michael, I have one comment in-line (see below), but other than that I can 
only say that I chose GPL for my own project.  It may discourage use of my 
code for commercial purposes but it might even be pretentious to expect that 
something like that would ever happen.  On the other hand, I was more 
interested in the advantages of open-source and I wanted to enforce that as 
much as possible.  I did some research of my own at the time (recently, 
actually) but I didn't go much into details and I didn't study other 
licenses in detail either, but I chose GPL in large part because it is the 
most widely used.

I tried to find some of the web pages that I read when I was doing my 
research but I couldn't.  However, I stumbled upon an article that I didn't 
see before and that is very much in line with my thoughts.  Here's a link: 
http://www.dwheeler.com/essays/gpl-compatible.html.

Hope this helps,

Dan

Michael, I think it's going to be hard to get what you want.  I don't see 
how you can give a lot of freedom ("I don't want to prevent people using my 
work in commercial settings") and, at the same time, achieve something like 
"to prevent people selling derivative works where my stuff forms the 
substantial part of the poduct".  I'm no lawyer, but I don't think you can 
define in a license what is a "substantial part of the product".
