From Dust: NoUbisoft, cleverly, has done it again.
Before the release of the PC version of From Dust, they confirmed that the title would require a one-time Internet activation only.

Oh, and in other news, the port is shit. Lousy control, Frame rates, no anti-aliasing--that should be enough.
Well done, Ubisoft. Their new slogan: where great ideas go to die.
