Many would argue that plugins are a derived work of WP and must use a 
GPL compatible license since we don't have an API exception spelled out. 
  Note that Creative Commons licenses are not GPL compatible and not 
usually recommended for source code licensing. There are many opinions 
on the matter though.  The safest thing is to GPL your plugins since WP 
itself is GPLed. This also gives you the best feel good karma since you 
are extending something on the same terms that it was given to you.  I 
personally don't bother with plugins that aren't GPL and won't integrate 
any of their code into WP so as to avoid license taint.  I don't get all 
hot and bothered about the licensing though. I'll leave that to others. 
  GPL compatibility of plugins/modules is always a great topic for 
heating up mailing lists.  :-)
