By magically I mean they connect via USB cables and apparently Windows has enough brains to understand their language. If you have a Windows box in your stack, you could get it to run a shutdown script that tells the Linux boxes (via telnet, ICMP or whatever) to shut down in turn. It's a kludge, but it would work and it probably wouldn't be too hard to rig.
