Tina Gasperson writes "GPU is a Gnutella client that creates ad-hoc supercomputers by allowing individual PCs on the network to share CPU resources with each other. That's intriguing enough, but the really interesting thing about GPU is the license its developers have given it. They call it a 'no military use' modified version of the GNU General Public License (GPL). The developers told Newsforge why they did it, with commentary from OSI and FSF." Newsforge is also owned by OSTG, Slashdot's parent company.
