xdvipdfmx locates the fonts using Fontconfig, just like xetex does,  
so no MAP files are needed....

....and it builds the CMAP resources for them on the fly. (Have you  
actually examined/tried this stuff, or are you just speculating?)

That's what XeTeX is about (partly, anyhow) -- being free to use  
fonts *without* any of this complex and confusing TeX-related font  
configuration process.

Users might well want Ghostscript installed, for various reasons such  
as previewing the PDF output that is created, converting graphics  
between EPS and PDF, etc., but as far as running XeTeX is concerned  
it is not a requirement.
