[SciPy-user] Re-releasing Python Equations under a new license?

Can I get any advice on which software license to distribute
my code? The sourceforge URL, which I forgot to post before, is
I'm just interested in feedback from users, whether someone uses
the code in a commercial application is not particulary important
to me personally. I would like people to know where to get the
source code itself if someone does redistribute, again so that
the chance of feedback on the source code is increased.
I'm not chained to the GPL, I'm just naive and inexperienced.
Any advice would be greatly appreciated, and my thanks to
Glen Mabey for his thoughts below. Re-releasing would happen
this weekend if I knew which license to use other than the GPL.

Well, the tradeoff is that with the GPL you may turn away a good number
of people who would otherwise have used and contributed to your project.
I understand that contributions are a major source of strength to a
project, yet contributors need to be attracted. One of the great
attractions of Python, numpy, scipy, and matplotlib for me is the
ability to use it in commercial applications.
Still others feel that GPL isn't as "free" (or liberal) of a software
license as the Python license, so for them it is a matter of ideology.
But, don't take my word for it. I suggest you again post to the numpy
list and explain your position. Ask whether your choice of license
would impact others' willingness to contribute to your project. This is
really a great forum to ask on, because those on it are already using
scipy and weave and hence are the most likely to try your project. And
many of them are actively developing code and contributing it to the
project, even though it is not GPL'ed ... like I have.
