Just don't switch the line you are powered from :)

There are lots of opto-isolated relay boards out there. You just need relays that can handle the voltage/current requirements. Here's one I found: http://www.ozitronics.com/relay.html (there are several on this page, at least one that can handle 240v.)

I don't know that I've ever tried gumstix to gumstix before, but in a
scientific test from a gumstix to my sony ericsson s710a, I got about
from the mouth of Gordon's garage to roughly where the chicken coop
is, which is probably 8 or 9 meters.

I haven't, but I've long thought about trying to power a gumstix
setup inductively from next to a 110 or 220v power line.  I think the
