Another way to accomplish the same goal(abi stability) is to use cppcomponents (www.github.com/jbandela/cppcomponents/), which is a c++11 library that does this internally while presenting you with a high-level interface where you can use all your favorite standard types (string,vector,tuple,etc) and have them work even across different compilers and standard libraries.
