Yes.

Wouldn't that again require patching the listings package, so that it
knows about the additional language?

When describing lstlang0.sty, the listings documentation refers to a
"Developer's guide".  The documentation available via texdoc listings
doesn't seem to contain that Developer's guide, but section 7 describes
how to compile the guide.  Maybe listings already includes means to
easily add new languages without patching the package?

I haven't read the Developer's guide so far, but I've uploaded my Lua
language definitions to
<URL:http://home.arcor.de/mailing_list/Downloads/LaTeX/listings-lua.zip>.
Feel free to adapt the files to make the Lua language easily accessible
from within the listings package.

Note, listings-lua.sty uses \lstdefinelanguage instead of
\lst at definelanguage (with the @).  Just replacing the macro in the
current .sty file makes the language unavailable, though.
