Anthony,

Yes, there have been several comparisons of Rasch measures and physical 
measures. Here are two:
http://www.rasch.org/rmt/rmt71b.htm - physical distance
http://www.rasch.org/rmt/rmt112a.htm - physical weight

But would be delighted if you would conduct your height experiment and tell 
us about it.

I'd love to see what happens. Pairing persons heights in cm and their Rasch 
heights simultaneously on a vertical line and comparing the calibrations 
give a good test of Rasch's interval scaling, I guess.
