It's another one of those "download if you're a subscriber" things I think, but the demo for Bioshock is on Fileplanet now. Also new nVidia drivers are out (faster to get them from the beta section on the nVidia website than from the FilePlanet download) with some BioShock specific improvements.

How good is the demo? I'll tell you when the download starts in 33 minutes or so :) Unless I find the same file elsewhere (*cough*tpb*cough*).
