Analog rack backplane idea?

[John Speth]

Has anybody out there ever thought out, analyzed, or even built an analog synth using a backplane rack?  By this I mean bussing a bunch analog function cards into something like the form factor of the old S-100 bus for a semi-custom loading of an instrument.  I realize it is an inefficient use of backplane conductors.  But does anybody have any thoughts or experiences about why this could be a bad idea.  It would make for real clean wiring.
