You might have a look at AFIO too :)

You can build non-blocking and synchronous i/o from a decent async 
i/o platform, as indeed QNX or the NT kernel have done. For 
standardisation purposes, I'd personally aim exclusively for async 
only and once that's satisfactory I'd build other abstractions on 
top.

All that said, I agree that Boost.iostreams' fundamental design 
failure is that it wasn't built atop a 100% async i/o framework like 
ASIO. Which is a shame, as STL iostreams could do with being 
replaced.
