Which explains why someone reported big-time ground loop problems
on a multi-floor net.

We really should do it properly.  DC-DC for the AUI is my vote.  
Digi-key lists a few - from US$10.00 to US$60.00 apiece.  (In
quantities of 10 or more.)  Wow. That's an expensive vote.  Tell 
me they're not that much...

There must be a cheaper alternative with Linear Tech, Maxim, NatSemi,
Motorola, and TI pumping out switching regulator chips.
