I don't understand why independant control
would be advantagous.  The EDM was going
to be done raster not vector.

However - I agree that extra wires would
be cool.

Make it like a 24 pin dot matrix printer
(pins offset so they dont inter-pin-spark)

Knock out an EDM in pages per minute 
rather than minutes per page.  I knew
there was a reason I wanted 3 phase power
in my shed :D
