Fisrt as sayed allready on this thread the spirit of GPL says you should put your code under the GPL.
This is use(no pun intended) not Modification, Copying or Distribution. The GPL verson 2 does not give you any rights to use the GPLed works(I'm useing my memory from when I read it a long time ago and skiming threw it looking for this. If I'm wronge please correct me). Does You're copyright laws give you the right to use Copyrighted works with out explicit permision?
