RE: AW: License proposal

>I think so - and I personally believe its what we want: Everybody can ship 
barracuda, can use its classes in closed/commercial software - but 
enhancements to the core have to be released. While the latter one is 
diffcult to ensure, at least nobody can take it and say "Look, we've got
this 
cool MVC Framework SHARK, and you only have to pay $1000 for it".

Not quite, and this is where the legal hairsplitting begins.

For example, if you modify a class, LGPL requires you to ship the source of
the modification. If you add a subclass that modifies the behavior of
Barracuda for your own use and leaves the rest intact, you do not have to
ship the source of that subclass. If you add an entirely new package, you do
not have to ship the source of that package.

The Apache license removes this ambiguity.
