It seems that LuaTeX is in general limited to Roman scripts for now.
I think that's not true. There are packages such as lautex-ja (Japanese in
at least basic Chinese) and luatex-ko (Korean). Also, most recent
polyglossia introduces support for luatex, although it is still
experimental and might not work with all languages.
The list of known languages/scripts that does _not_ work with the latest LuaTeX (version 0.76 that
is part of the upcoming TeXLive 2013) I added to
http://wiki.lyx.org/LyX/LuaTeX
is taken from the most recent version of polyglossia. Moreover the polyglossia developer is also one
of the people that try to make LuaTeX working with RTL languages. It turns out that LuaTeX as it is
now is not yet able to fully support these languages.
Therefore I don't like that we default to dviluatex when the user checks the "use non-TeX" fonts
option in the document settings. XeTeX is now almost ready (except of some expert microtypography
features) and LuaTeX is apparently not. So we should default to XeTeX.
