Hmm, I suspect that some remix between my old (deprecated) Libertine in 
ConTeXt recipe and the ttf2tfm automatic unicode splitting would have 
some positive effects.

(I would discourage using that recipe for alphabetic (incl Roman) 
Unicode fonts because it blows away any kerning that would happen 
between unicode blocks. Is there less kerning among CJK fonts? I would 
expect so.)

Thinking aloud, you'd probably want to include some language-switching 
commands, to mediate between the calling of unicode fonts for un-named 
CJK glyphs (just raw conversion from Unicode to font switch + glyph 
number) to named roman (and other alphabetic) glyphs (conversion from 
UTF-8 to named glyphs to font+glyph, which retains kerning where it can).

I know it's sketchy and vague, but have a look inside font-uni. It's not 
the most complicated file in the distro.
