Roger Wilco, a popular voice communication program in the PC community which is often used to gain a significant advantage in multiplayer games, is now available in an alpha version for the Mac. CyberBob pointed out that some Bungie games are listed in the compatibility testing chart at the Roger Wilco site: all Marathon games, both Myth games, Oni and Halo. They don't yet supply any Mac base station (server) programs, and I hear that the Mac alpha isn't quite there yet... but here's to hoping they can get things squared away for the Mac side of the house.
