This is my project... not sure why it suddenly appeared on HN today, but happy to answer any questions.
There is a short talk from Fosdem https://www.youtube.com/watch?v=UZty3v4xVnQ and a longer one from last years Lua Workshop here http://2013.capitoledulibre.org/conferences/lua-workshop/tow...
One of my main ideas was to make things easier to understand by having everything in a scripting language; I chose Lua as the LuaJIT ffi had just come out. At some point porting it to other languages would be a good idea.
