Has anyone attempted to do multicasted distributed objects using NSSocketPort/NSPortCoder? I realize that is doesn't make sense generally, but it does make sense for sending oneway messages to a singleton in a large number of clients. I also realize that multicasting requires explicit treatment of dropped and mis-ordered messages...


I have coded a prototype which uses NSArchiver, but this technique does not support NSInvocation or byref objects.

Any insights will be greatly appreciated.

Take a look at Avis: http://avis.sourceforge.net/

Reliable multicasting is a notoriously expensive problem. Even if you send a one-way message, how do you know it was received and being processed over UDP multicast?

What limitation does your prototype impose so that it can't handle NSInvocations?

Cheers,
