For people just joining in, check out http://www.eluaproject.net/doc/v0.9/en_arch_ltr.html for a discussion of what eLua does already.

I ran into the problem in my Lua-FLTK days (4.0, 2001?), where my tolua binding created one table per class for its methods. Not very memory-friendly, and the data structures were not sharable across Lua invocations the way C shared libraries can be.
