[rescue] adding power redundancy to single power supply systems ?

[rescue at hawkmountain.net]

Did some searching... does anyone make a 'power strip' that takes two AC
feeds, has some relays/capacitor magic/etc and can flop between a primary
AC feed and a secondary AC feed to make single power supply systems take
advantage of multiple colocation power feeds ?

I never 'strike out' with this group...  hopefully this won't be the first
time for it :-)
