OK, then it looks doable. But then I'd take the next step and use
cents (100ths of a semitone) as the basic unit. This is already a
widely used unit in musical theory, and it will be sufficient even
when someone wants to implement 1/16 tones in the future (not me!).
There are more applications interesting more for MIDI generation than
for typesetting: one could define other than well-tempered scales, by
a simple redefinition of the note names. For typesetting the values
should be then be "rounded" to whatever the smallest displayable unit
is, probably quartertones.
Looks like a nice project for my christmas vacations...
