Supposing one has a farm of older, relatively slower machines (Sun-2's, Sun-3's, early SPARCs, 386es, very small VAXen, 68k-based Macs, etc.) running various Unixes (mostly NetBSD), networked together and connected to the Net. What does one do with it? I've been trying to think of some interesting, moderately useful distributed-computing project that they could sit and crank away at and haven't come up with much of anything. All the distributed projects that I know of are distributed because even fast machines aren't enough by themselves -- a trailing-edge farm can't make a useful contribution. If network Tierra (an artificial-life research project) had ever come to pass, that would have been a superb application for these beasts. But it didn't. Ideas, anyone? Please? --James B.
