I was thinking of looking into OS X and/or Clang support in the near future. The codebase seems good with the exception TR1 (now part of C++11) features shared_ptr (and array) inclusion juggling between Boost, MSVC, and GCC TR1 implementations. As Boost is a mandatory requirement, all of this seems quite unnecessary. On a related noted, there would a small optimization opportunity by using make_shared for shared_ptr allocations throughout the codebase.
