The "whole thing" cannot consist of plugins with incompatible licenses,
because AFAIK dynamic loading requires licenses to be compatible (correct me
if I'm, wrong).

Don't missunderstand me, I don't want to flame against any project. I have
exactly the same problems in my own software too. I just have the feeling,
that this GPLv2 vs GPLv3 topic is more complicated than it looks at a first
glance.

Yea, those are always a problem.
