Does it make ANY sense to SELL GPLed code?
The buyer is allowed to modify the code and redistribute it as long as
comes with the license and the full source.
Assume you start selling octave with GPL. As far as I can see
somebody can buy it and redistribute it for free.
Am I wrong?

All this License stuff makes me sick.
It takes more time to figure out how I can use what under which
conditions than just doing something even if is FREE code.
The nice thing once I started with Linux and all the FREE stuff 
was that you really didn't have to care about all this crap 
just do something and it worked marvellous.
