There is a new project - AQUA@Home - team created here.
Edit: No checkpointing yet. Original tasks incorrectly estimate is 1400 hrs per task but this is/has been corrected to approx 1-2hrs. They appear to be using the cheater friendly BOINC Scoring System (where the floating point speed can be manipulated to a ridiculously high figure and gain absurdly high points. It looks like the Proj Admin will change this system.
Apps available for linux and windows.
