Yes, assuming one of those implementation's licenses is compatible with the plugin, or the plugin is written to a generic interface and thus is a derived work of the generic interface as opposed to the implementation of that interface. > BTW, what is the FSF's position on programs communicating using > CORBA-like methods? I don't know if they've really come out and said yet. I suppose there are cases where a corba-like method wouldn't be subject to GPL being applied to the work as a whole, and cases where it would. You probably should ask the FSF for their opinion.
