This is more complex than that. You may be able to run a business 
selling only service but if you run a restaurant you can't serve empty 
plates. I plan to make some kind of "plugin store" where i can sell 
plugin dev both on demand and on shelf, which is not something possible

The idea of a plugin store might sound to an open source community like 
the devil, but truely for your community it's free testing and 
debugging, and most probably free pull requests for all existing OS 
plugins that I find not good enough, but not profitable to rewrite.
