No it doesn't change any behaviour, I should have made that clear.  We just extend the API with specializedversion of connect() which connect to receivers
not derived from ppReceiver.  Code using the normal version
of connect() would continue to work as before.

Well, you're the one who has to maintain the code, so I guess its your call.

Yeah, what I had in my head was that we shoudn't break that.  Not that the Gtk-- people would break it.

Well, if I was on their mailing list, and if they were still designing rather than coding I wouldbe telling them "USE CORBA".  As it is they use their own
system.   The similiarity between
messages in Mnemonic  and ours is that the sender just sends a message without caring who
gets it.   The cool thing which Mnemonic does is that the Message system detects when no
one is listen to a signal which has been emited, and tries to load a module to handle the signal.
Not that any of this has anything to do with us.

Yeah, OO is cool.   None of this overlaps with what CORBA does though.

I must say I am a little surprised you like the idea, I just put it up as a throwaway "crazy idea".
But  if you like it, I suggest you talk to the Gtk-- people about it and then put a joint post
onto comp.os.linux.announce and other places, and get the project going.

We should get it off the PenguinPlay list though, since it is not really a game programming
issue.
