Are you confusing it with the UltraSwarm/GridSmarm stuff http://cswww.essex.ac.uk/staff/owen/research.htm#The%20Flying%20Gridswarm,%20and%20the%20UltraSwarm (which at the time it got all the publicity, wasn't a grid - it was 1 machine with a flight time of about 45 seconds). Gumstix are fantastic, but IMO they're more appropriate for custom apps - robotics, wearables, drones, things like the 'Pegasus' project : ( http://www.pegasushabproject.org.uk/ ) than for general purpose computing. For your Simon thing, I'd go for a p100 and some serial cables (killjoy I know, but you'll be less annoyed when it's stolen or puked on). Maybe some IRDA recievers in each skull and a TV remote for the 'wand'? A dozen 'stix in a cluster has about the same computing power of a so-so pentium3, and costs probably 3 times the price a Sun T2000 (once you sort the networking out). That said, they're perfectly able to compile stuff themselves - storage more than memory is your limiting factor, so just use an NFS share. Alternatively, I had a lot of success cross-compiling ARM packages with the stuff from http://scratchbox.org -- Rasputin :: Jack of All Trades - Master of Nuns http://number9.hellooperator.net/
