A friend of mine was testing Revolutions tools at his job recently and found a few frustration points: namely its based upon a relatively old version of R, and while they allege to support larger than ram numerics, its apparently quite thrashy. [there some interesting subtleties to supporting larger than ram computation well enough for it to beat distributed, which i'm trying to do for my own work, so I found it quite exciting to hear that current analytical tooling vendors dont do it terribly well :) ]
