16px default, SI meter (Re: platform-specific font size issues)

If you are looking for a new definition for the reference pixel, perhaps, like DSSSL and early XSL, CSS lengths could be based on the SI meter? Or are inches becoming a U.N. recommendation? :-)

Microsoft tried something like this in MSIE 4.0 Mac, where 'medium' was increased to 14. They changed it back to 12 in version 4.01.

I don't know about UNIX setups, but your suggestion seems to work fine with the new 1.2 scaling factor between keywords in CSS2 [1]:

xx-small  9.24 (for most fonts, the smallest readable size on a Mac)
x-small  11.08
small    13.33
medium   16
large    19.2
x-large  23.04
xx-large 27.65

(My only worry is that such large type takes up so much screen real estate that it might make navigation slower and more complex on all but the most high-end setups for many years to come.)
