Yes, pango can use X calls, but Emacs have to convert to using pango, and 
that is a lot of code.  Basically you would have one pango version and one 
X version of the code, or just one pango version.  I don't know if the 
requirement to have pango to run Emacs is OK.  Also, Emacs would probably 
have to be converted to Unicode, since that is what pango uses.

If you say so, I haven't looked at Xft2.  I don't even like antialiased 
fonts, they make my eyes hurt :-)
