"Shack: Is a public server going to be released for people to run, or will it be peer-to-peer? If a dedicated public server will be available, will there be a linux version as well as Win32?
Randy Pitchford: Sean (Reardon), Steve (Jones) and Jimmy (Sieben) have worked really hard and long on the new networking system for Halo. Because of their work, there will be a dedicated server as well as a bunch of other cool features. The game will be launched to run on the Windows platform with a Mac version planned to launch at the same time. The PC version will definitely offer the dedicated server. Offering a dedicated server for other platforms is not as likely at launch."
