Ask Slashdot: "Be" is for Beowulf?

PhiberOptik asks: "Considering that BeOS is so adept at handling high I/O and network bandwidth, whould it make a good OS for a Beowulf cluster? I know that since BeOS is not open-source it would be harder to have applications made, but they would be easier to maintain; as BeOS has a standard set. Any ideas?" Could this be done? What OS characteristics are necessary for a Beowulf cluster?
