Well, the luaforge library is MIT licensed (same as Lua) so no problem
there. The library itself is modularized into files which is good and
bad, mostly good when it comes to LPeg. My feeling on LPeg is that
Nmap will eventually have it because Lua will eventually have it.
Plus, LPeg is appropriate for most parsing problems (JSON fits nicely)
that are network related. What we are waiting for is a library/script
that heavily relies on it that justifies the addition of LPeg. The
JSON library may have been that library :)

[If we add LPeg sooner rather than later we will have wider adoption
which in my opinion is a good thing. Lua patterns are too weak for
parsing (see script arguments code for case in point).]
