Be careful what you wish for.  XeTeX is very useful, but on MacOS X
you can't run it in a terminal session because it uses the system
fonts and rendering that are only available.   Future TeX systems
that use system fonts, parallel processing, and the graphics
processor (for faster compilations) will not come without some
