[time-nuts] any way to bootstrap a frequency standard into a, voltage or resistance standard?

It's nowhere near the idea of a Josephson array, but if a NIST-traceable 10V +-10uV reference is good enough to satisfy your voltage-nut urges, you can buy it from www.gellerlabs.com for $35.
I also have a few standard resistors (e.g. 1.000002 ohms) that I'd be interested in calibrating, but I can't seem to come up with a practical way of doing it.
Frustrating, isn't it? :-)
