This post raised some concerns for me since i have a Python extension
that i was going to add to our latest product release. The product is
not written in Python, nor does it require Python to be running and
the extension is there because i thought it was cool. However, i have
to ask whether it is legal to retain this functionality.

I don't understand this. What is "the software"? As far as i can tell,
if the software is distributed in binary format (say as a DLL on
Windoze boxes) then it can be distributed freely with no conditions.
I've written an extension to a vehicle tracking product that we
produce that offers a scripting interface. I'm not sure if anyone will
use this, but i certainly can't distribute it if i have to distribute
the Python source. Added to which, i don't want to distribute my
source (except to selected folk) as i don't need the support grief.

I can't forbid commercial use. This was why i chose Python. I have no
idea if people can or will  make money on my interface. If Python
imposes commercial limitations then i'll have to drop it, pissed-ly,
since i spent quite a bit of time writing an extension, but that's the
way it goes.

So, can somebody tell me if i can ship the Python Bits and my own DLL
to anybody to use in any way they desire? No fairly otherwise eh?
