If I use \unexpanded it fails:
This is luaTeX, Version 3.141592-snapshot-2007042614 (Web2C 7.5.6)
(lua-tex.tex
! Argument of \\ has an extra }.
<inserted text>
                \par
<to be read again>
                   }
Throw out the \expandafter.  It basically negates the effect of
\unexpanded by having expansion occur afterwards.

Namely:

\def\lua#1{\directlua0{\unexpanded{#1}}}
