No, it wouldn't.  It would unnecessarily restrict the users.  The POV Team
is NOT Microsoft.

As it is, ABX is right.  Assuming they are written correctly, using *any*
units.inc file and interchanging them will work without a hitch.  I even
wrote one that allows you to define the actual unit size for inch, which all
others are based off of.

Ie, (pseudocode follows)

If inch is not defined,
    inch = 1/12

foot = inch*12
yard = foot*3
mile = foot*5280

etc

So you could scale them to fit objects which have not been unitized.
