We received a new press release from Valve, announcing the expected end of beta testing of the Steam content delivery platform. When the full version launches next week, you'll need an actual valid CD-Key to continue playing Half-Life and Counter-Strike through the system. Here's the full message

The Steam Beta has delivered several Valve games and popular Half-Life MODs to over 300,000 gamers, and will come to a close Tuesday evening (Pacific Daylight Time). The first full version of Steam, Valve's broadband platform for the delivery and management of digital content, will launch at 11 am PDT on Wednesday. Set up installers for the full version, which will be free of charge to existing Half-Life and Counter-Strike players, will be available from www.steampowered.com and leading game sites. Anyone interested in hosting the installer or becoming a Steam Service Provider, please email biz@steampowered.com. Valve would like to extend its thanks to everyone who participated in this beta.
