I have taken a sophomoric glance at openType (and some of this might 
apply to trueType).  It specifies (for example) three ways to calculate 
vertical leading: the right way, the Windows way and the Mac way.  The 
latter two are there for "compatibility" reasons.  This is complicated 
by the indication that the Windows way is sometimes used to detect 
overlap.

This is only a trivial part of the whole problem, but I would expect 
that it would be possible to get font table info in either OS.  Perhaps 
some uniform calculations can then be made for some metric values.

I have no idea how useful those metics would be in writing to the 
screen and the printer using interesting (eg. unicode friendly) APIs.

Just babbling.
