gridMathematica Announced

simpl3x writes "Mathematica for grids was announced at Comdex. It offers support for the usual platforms--Windows, OS X, Linux, and Unix--and offers the ability to use heterogeneous OSes. I haven't used the product in years, but cool nonetheless. Does an off-the-shelf software package, which is scalable as this is provide competition to custom packages--is it easier to add machines than develop custom programs?" And just when you thought Comdex was good and dead.
