I suggested a similar thing privately to Mariss a year ago
(ie two bits from the computer, decoding to four to
enable a 'transmission change' to allow different
speeds for machining vs rapids).

Basically, high precision steps are used for machining,
and low precision (but far moving) steps would be used
for rapids.

He didn't like the idea then, but I still think it
is a great idea. Assuming each axis has to come to
a complete stop first, I presume the problem might
be loosing steps by launching into a higher gear at
a non-integer step multiple of the higher gear
(something that can be accomodated in software on
the PC side, with a little attention).
