Right, I'm not an C programmer...
And it doesn't look like it violates the license to release context free 
patches or (detailed) explanations how to fix an issue. How would you 
otherwise be possible to use Bea yourself with jack? Is this 
hypocritical or just the way it is (I'm wondering about this)...

Ok, the main problem is that is isn't GPL, I agree for 100%. But why is 
there a beatrix website if he doesn't want anyone to use it? And why 
offer an app which is not very useful atm? Isn't he 1) more concerned 
about not using the code in other software or having different versions 
of bea around the internet? Does he really care about 2) these little 
fixes which makes it able to use the same app with jack? To me it sounds 
like he is more concerned about the first...
