Pozor. Mam takovy pocit, ze GPL neomezuje prodej - jenom uklada omezeni, 
ze pokud neco prodam, nesmim kupujiciho omezit v pravech na modifikaci a 
distribuci.

To, ze je to pod GPL, neznamena, ze to nemuze byt komercni. Jenom se na 
tom neda tolik narejzovat.

Relevantny vynatek:

Q: If I use a piece of software that has been obtained under the GNU GPL, 
am I allowed to modify the original code into a new program, then 
distribute and sell that new program commercially?

A: You are allowed to sell copies of the modified program commercially, 
but only under the terms of the GNU GPL. Thus, for instance, you must make 
the source code available to the users of the program as described in the 
GPL, and they must be allowed to redistribute and modify it as described 
in the GPL.
These requirements are the condition for including the GPL-covered code 
you received in a program of your own.
