[PD] PD license technicalities with regard to selling a project...

[Hans-Christoph Steiner]

The GNU GPL or the BSD License puts no restrictions on selling the  
software as long as you follow the conditions of the licenses.  For  
BSD, its to include the copyright notice with any distribution, for the  
GPL, you are required to distribute the source of derivative works.  I  
think that Pd patches could remain closed source if you want, but  
modifications to the GPL parts would have to be released.

"If nature has made any one thing less susceptible than all others of  
exclusive property, it is the action of the thinking power called an  
idea, which an individual may exclusively possess as long as he keeps  
it to himself; but the moment it is divulged, it forces itself into the  
possession of everyone, and the receiver cannot dispossess himself of  
it."
