I do not want to make the support for a specific framework like Kepler opr Orbit. I'd rather make it lowest common denominator like WSAPI so folks can run whatever type of Lua web development toolkit they want on top of this system.

I'd like it to be super easy for folks to just throw CGILua scripts in their doc root as well as lua server pages *.{ls,lp} and have them just work. But I'd also like more advanced folks to be able to tweak and write their own WSAPI handlerss so they can run whatever framework they like.

Another vote for supporting wsapi *and* the nginx-lua module (preferably
bundled up with a bunch of stuff eg like
https://github.com/agentzh/ngx_openresty). The Lua nginx support is
really useful even when you are using a different backend, eg
