Ok, will do.

I'm through with the list [1].

My current favourites are MessagePack [2] and cmsgpack [3], because
this has the prospect of offering both a pure Lua and a C library, it's
for 5.1 to 5.3, and has excellent support in a wide variety of
languages. Need to get into testing and see if msgpack doesn't impose
unacceptable limits for me to sacrifice the readability of Lua.
