The Bash and Slash Forums have details on how dedicated servers will work for Red Orchestra 2: Heroes of Stalingrad, Tripwire Interactive's upcoming military shooter sequel. According to the explanation of someone claiming to be a member of the beta team, the game will support both ranked and unranked servers. Anyone can run either kind of server, though Tripwire will be monitoring ranked servers, and will boot them if they engage in shenanigans. Also, a post on PBBans based on a TWI conference on competitive gaming explains the game's anti-cheating plans (thanks Joao). Word is:

This is the first game (That I know of) to use both VAC and PunkBuster. I'm very happy that Tripwire decided to use both because I know the competitive community prefers using PunkBuster because of the additional functionality and streaming. Tripwire has gained a lot of my respect for listening to competitive gamers and PC gamers in general.

Lets hope other developers that favor VAC will see the light and offer players a choice in anti-cheat.
