Have you looked at the source for Apple's Bonjour? <http://developer.apple.com/opensource/> <http://opensource.apple.com/source/mDNSResponder/mDNSResponder-258.18/> Might be interesting to see how it does announcement/discovery. Or maybe just use it directly, if this happens to be a case of "gee, I didn't know that wheel had already been invented." :-) sherm-- -- Sherm Pendley <http://camelbones.sourceforge.net> Cocoa Developer -- http://mail.python.org/mailman/listinfo/python-list
