The Globus Project and Computational Grids?

SigmoidCurve asks: "The latest issue of The Economist (sorry no URL, using the quaint paper version) has an article about software used to create 'computational grids' like those used with SETI@home. They mention the Globus project which is released under an open source license. The Economist article speculates on the future of the Grid and what kinds of projects would benefit from becoming massively parallelized. What does the Slashdot community think of this and similar projects? Does anyone have any comments about Globus or other such software? What projects do you know about that could take advantage of the untold billions of idle processor cycles lying in wait?"
