Just wanted to apologize for my message of yesterday, I think the idea of "subterfuge" got me started. What makes me feel bad is that there is the open-source people, the shareware people and the big companies... and what I'm seeing is the big companies using open source to drive the small guys into the ground... IBM pushes open source, Google pushes open source, Intel too... And then, in between the expensive and the free, there is no space left to make a living for people starting up.

But at the end of the day, you guys came up with the code, you're free to do whatever you want with it.

I'll try and be more productive next time I chime in ;)
Keep up the good work!

But from what I read, I think I'll stay away from this library. You guys 
know your subject really well and this library is most probably the main 
reference on the subject. So, it would seem like a logical package to 
look at for any application that wants to do anything remotely related 
to panoramas.
    

I don't mean to scare anyone off, and I have only contributed a few minor
suggestions and a sprinkling of code to PanoTools, so obviously my
thoughts are my own.  However, I think you'll find that the main
contributors are all decent people, who just want the license they
contribute under respected. It's as simple as the old school yard adage:
if you take, give back.

  
But then, if there is any chance that the software could make a penny, 
then the use of your library might simply jeopardize the whole business. 
This last comment about what constitutes a subterfuge and what doesn't 
is very scary, I bet that if you pay your lawyer enough, then any use of 
panotools (even through fork/exec) could be presented as a subterfuge 
and the "offending" software would have to fall into open source.
    

Those are RMS's words, not mine, but they do point out that getting
around the license with technical arguments isn't productive.  It's
not productive legally, but moreover it's not productive for the
community.

  
I'm worried that such a lawyer might even sue people doing similar 
features who would have learned the techniques from reading your code.
    

The only intent here is to respect the terms of the license, which
aren't that extreme.  They don't, for instance, prohibit anyone from
making money off the library (nor should they, IMO).  This is not some
vague and ominous "Intellectual Property" cloud such as the one iPix
had hanging over this field for years (and which no doubt someone else
will take up as soon as they buy the rights to that IP at the yard
sale).  There is no patenting of software ideas, no control over how
you use the software, no "protection money" racket if you build it
using >180 deg images, etc.  It's truly simple: if you want to use the
code to make your program, you must contribute your addition under the
same license, or follow the rule of using fork/exec to keep them
separate.  That's really it.

  
Some people can afford to donate their time, some people can't. I would 
have hoped that you guys would be able to find a less hardline position 
where, for example, those who make money out of linking panotools might 
contribute some $ to help run the initiative. After all, non-profit 
doesn't mean no-income.
    

People who donate their time to GPL projects typically do it because of
the sense that they are contributing to a greater good, that their
contributions will remain open and free, and that others who add to
their improvements will donate those improvements back in kind.
There's nothing sinister about it.  That's what motivates me in the
free software projects I contribute to.
