It should be fairly easy to make XeTeX instruct FontConfig/Core Text to
look for fonts under TEXMF tree, but I'm worried that some fonts there
are not built with the idea that they would be exposed to system
libraries and may be badly built (AFAIK that is the reason distributions
don't just added those fonts to FontConfig search paths).
