Is There a Use for a Public Beowulf?

Anonymous Coward asks: "If the average Slashdot reader had access to a Beowulf cluster, what would they use it for? Everyone seems to think that Beowulf clusters are fairly interesting, but does anyone have any particular job they would assign to one? If someone were to create a publically accessible Beowulf cluster, what would you do with it? Is there even a demand for such a beast?" Now this would be a neat hack, but the logistics behind running such a thing would be immense. But even though something like this may not be needed now this might not necessarily be so in the future. Something like this might be a great tool for that novice astronomer in the neighborhood ... or aspiring mathematicians in high school.
