About offering the source code for a fee: I remember the guys at Ardour doing

source.
About the watermark: if it's very well hidden (or there are several instances

But then what? confront the offender? After saying he's sorry, then what?
What I'm saying is I wonder if it's effective.
The creators of Frogatto seem to have a good model.
