Another option has occurred to me, remembering that XeTeX allows quote 
marks to be used around \font (and \input) names, as they may need to 
include spaces:

4) make \font sensitive to whether the font name is quoted (with "..." 
or '...'), looking first for a .tfm file if no quote marks were used, 
and an ATSUI font if they were.

This is almost like (2), in that it makes it possible to control the 
behavior from the source document; it's conceivable that you might want 
to experiment with using cmr10 in AAT mode as well as TFM mode, for 
example, or you might have tfm files with names like "Helvetica.tfm". 
It's a little different in that
	\font\myfont=Helvetica at 10pt
will not ONLY try for Helvetica.tfm, but ALSO look for an installed 
Helvetica if no tfm is found.

I think I'm going to experiment with implementing this; it should make 
standard documents (plain TeX, LaTeX, whatever) all work as expected, 
as they won't have quote marks on the font names, while also offering 
the virtually-transparent use of ATSUI fonts that has been a goal all 
along.

Comments still welcome!
