Their idea reminded of a similar concept I heard once: open source scientific papers.<p>It works like this: you put up the .tex source, the data files, the R, Octave, etc. scripts, and if people download and run the scripts, they get the exact paper as a result, including all the graphs. This way one can check that the graphs really show what is claimed in the paper and that there has been no bug or "polishing" of the results.
