Hi Bob,

Your description is exactly what I was thinking of.  I'd be very interested
in seeing what you've got so far.

Have you got the H bridge FET drive stuff fully worked out?  I have some
specific ideas in this area, seems to me that it should be possible to make
a very high current H bridge by using MOSFETs that can have on resistances
of 0.03 Ohms!
