Dear friends from the past :-) I have been using XeTeX for my projects involving Greek, Hebrew and Arabic, for years, mainly because of TECkit, but there are things that I can't avoid and that are quite annoying. For example, when there is a [some Greek letter]+beta -> \1 medial beta ligature in the font (which is essential for Greek), and the word happens to be hyphenated between \1 and the beta, then the beta becomes initial again. This is very annoying, and Omega would never do that.
So I'm currently slowly migrating to LuaTeX, under the guidance of Javier Bezos. There is another VERY useful feature in LuaTeX: I can decide which PUA characters are right-to-left letters, so I can draw my own Hebrew glyphs, map them to characters in the PUA, and they behave correctly with respect to direction. XeTeX does not allow that.
