Hi Will, 
don't be worried too much about the missing accents.  This is a
special case.  People writing Chinese, Japanese, Arabic,... won't miss
them anyway. :)

Yes, that would be great.

I'm not so much concerned about what's in minimal TeX distributions.
ATM I'm working on a TeX system which is running inside another
program.  LuaTeX is running in the background and people expect to get
a result immediately.  Neither the calculations done with Lua nor the
actual typesetting consume a significant amount of time.  The system
spends at least 80% of the time loading fonts.  It would be quite
helpful if I can avoid at least loading fonts I never use.

I already considered to prepare a LuaTeX font cache file which
pretends that Latin Modern has no glyphs. :)

Another thing I thought about is to prepare a dedicated format file.
But I don't have much experience with LuaTeX yet and don't know
whether OpenType fonts can be loaded into the format file at all, and
if yes, whether it speeds up things significantly.  There is much to
explore...

Regards,
  Reinhard

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
