With shared it's trivial on windows and linux, altho there's no 
cross-version communication. With a custom VM it's trivial everywhere 
altho you won't be able to use C modules, but you do get cross-version 
communication (a la `require "5.3".load('return require 
"5.1".loadstring("return 1")()')()`).
