The BioShock demo is now officially available, after a poorly executed embargo that prompted a request on The Cult of Rapture that folks hold off until now in order to ensure the availability of proper video drivers. On that topic, the NVIDIA beta drivers with BioShock support are here and the ATI drivers are here. As for the demo itself, the 1.84 GB download is available from 3D Downloads, AusGamers, FanGaming, FileFront, FilePlanet (registration required), GameDaily, Gamer's Hell, GameSpot (registration required), Gameworld Network, and PixelRage. The demo is also available via Steam.
