This can be solved. It's possible to add some special exemptions to the 
GPL for certain applications. But I guess it would be possible to add 
exemptions for a certain subset of the API. So an extension that would 
use only the limited "super free" API could use any license.


PS: I'm not to keen on signing a contract that allows anyone else to 
make directly money from my code. Why should the Association be able to 
sell licence I wrote in the spirit of true open source (GPL)? Changes 
from GPLv2 to v3 are not to worry, but the prospect of commercial 
licences worries me unless the contract has a compensation clause for 
the developers. But don't worry to much, I probably won't write code for 
5.0. I'm just an interested bystander ;-)
