6. Switch CayenneModeler to platonos plugin engine. There were some concerns regarding Platonos (and we may end up maintaining it on our own), but I haven't seen any workable alternatives proposed.
As I mentioned earlier, JPF seems like a better (and not abandoned) alternative: http://jpf.sourceforge.net/
And NO, there's no license problem, as the plug-ins (Cayenne Modeler) doesn't have to have the same license as the "platform" itself (it's just like Eclipse). Ahmed.
