[boost] Functionality for part 7(a) of Boost.IOStreams Roadmap

Boost Experts, I think I possibly addressed the "output" part of requirement 7(a) (Support for asynchronous and non-blocking I/O :: asio compatibility) from the Iostreams Roadmap https://svn.boost.org/trac/boost/wiki/IostreamsRoadmap in this library https://code.google.com/p/async-ostream/ Do you think it addresses that requirement from the roadmap? If yes, does it make sense if I make a patch for Boost.Iostreams to include those five files? Regards, Gene
