Re: License Question

[Mitchell Baker]

The Mozilla Public License allows one to charge for executable versions of products built using MPL code.  The source version of MPL code must always be available free of charge under the MPL.  But one is allowed take that source code, compile it and sell the executables.  this may be hard since others can do the same.  But if you have the brand, or user base that will pay for this, then one is free to do it.

And of course, one can combine MPL code with other code into a product and charge for the combined product; a number of companies do this.

Hello,

I'm a newbie in License considerations.

Does exists an OpenSource license which allow to be paid if the Sofware is
used in a commercial application ?
Thanks,

No there isn't. But it may be possible to use an Open Source license in 
conjunction with a closed license to achieve the same thing. It depends upon 
the nature of your software, and what you consider "commercial."

Trolltech licenses its Qt library under a dual QPL/GPL license. The only way 
you can use it for your own software is to make your stuff open source. If 
you want to release closed source software using Qt, you must purchase the 
professional license for quite a few dollars.

Commercial software is NOT the same thing as closed source. But 99% of it in 
the real world is. A scheme like Trolltech's may work for you if your 
software is used for the creation of other software.
