  I wonder if it would be possible (and practical) to use a
microcontroller, perhaps a PIC, to act as a core controller. Use the
A/D and D/A hardware to handle the drive and sense stuff, and do all
the timing in firmware...making it easily tweakable.

  That would be something I'd be up for trying...if I can find a chunk
of core of low enough density to trace the wiring in. There are some
nice low-density planes on eBay right now, but they are priced WAY too
high in my opinion.
