While Butcher has advised me that this is old news, I'm posting it in blatant defiance of his better judgement. Inside Mac Games has posted an item on Microsoft's DirectPlay, and Apple's answer to it:

A couple of years ago, Bungie developed a cross-platform game networking API called Uber ...

Apple has picked up Uber and is now developing it as OpenPlay, a network abstraction layer for both the Mac OS and Windows that game developers can use in their games to make them network across both major operating system platforms. Since the technology is available under Apple's Open Source license, developers do not have to pay a licensing fee to use OpenPlay, and they can also modify the source code to meet their needs.

Good to hear that Uber, the networking model I believe the Myth series was built on, is still under development. And even better to hear that Apple is positioning it against DirectPlay, which (in my uneducated opinion) reeks of an attempt to block out other platforms. An interested read, definitely worth stopping by.
