I've now got a Gumstix Stagecoach with six NFS root OMAP3-based boards up and running in my office. That brings the grand total up to ten Cortex-A8 based boards on the local network.
Eventually these or something similar will go up into the data centre but, until then, I might as well put them to use. Any suggestions? If you'd like access then drop me a line.
