I'm not *that* convinced.  XeTeX already uses an extended DVI format
and in order to fully support Thành's microtypographic extensions it
probably has to be extended even further.

Given that you can pass something to a PostScript interpreter through a
\special, I don't see any reason why it can't passed to a PDF file
through \pdfliteral or the like.

Pierre, I know that you share my opinion about the beauty of
PostScript.  Hence no lengthy discussions required.

Since TeX engines support PDF directly, supporting PostScript became
more and more inconvenient.  But for LuaTeX users there is a bright
star at the horizon:

  http://escrito.luatex.org/

It's a fully fledged PostScript interpreter written in Lua.  I tried
it today and it works like a charm.  Even the source code is beautiful.
Of course, it makes most sense to use it with LuaTeX, but LuaTeX is
the future anyway.

Regards,
  Reinhard
