Valve announced today that its Steamworks development suite is expanding with the introduction of Custom Executable Generation (CEG). Complimenting the already existing set of anti piracy tools in Steamworks, this does away with intrusive DRM, generating unique copies of games for each user, thereby allowing them to access the application on multiple machines without nagging install limits or having to install root kits.

“Delivering this extension of services on Steamworks first anniversary, demonstrates our commitment to continually develop the platform to better serve the community working with these tools,” said Gabe Newell, president and co-founder of Valve. “As we roll out these features, we continue to look for new ways make PC games easier to create and better for customers to experience.”

Last week, Valve made in-game downloadable content official on Steam. The Maw was the first game to offer such content and already publishers have begun to take advantage of the feature, including Ubisoft, which now sells the Fortunes pack for Far Cry 2 over Steam. Valve calls it an initiative at making DRM obsolete.
