If it Pyro pickles objects for transmission it should work with PyObjC objects, but only if the programmer writes custom __reduce__ methods. PyObjC objects are not pickleable by default, because I haven't found a way yet to translate the native Cocoa serialization support (NSCoding) into Python's pickle mechansim. Adding bonjour support on top of Pyro should then be easy enough: just use Cocoa's support classes for that. Ronald
