I'm sure I'm being stupid and underinformed, but it doesn't seem like these systems do anything you can't replicate easily enough with htcondor/gridengine and so-forth alongside cluster computing filesystems. It almost seems like Java people decided they wanted Java only in their stack, so they ignored all the existing unix cluster computing stuff. Somebody's downvoting me but I doubt they know anything about streaming and short-job support in gridengine.
