We've another speaker going to do a (short) talk tomorrow night.
Brian Shannon of digital demigods (http://digitaldemigods.com
) has been a member at a couple of X-Cake meetings already, but tomorrow he's going to give us an overview of his multi-player system.
Brian's system is a matchmaking server and multi-player protocol that will make it simple for iPhone developers to make their games network capable (think Playstation Network, or XBox Live for iPhone).
Brian is actively seeking early adopters to try out the technology, and would be happy to speak to iPhone game developers who are interested.
