Currently there is 
http://www.boost.org/libs/iostreams/doc/classes/mapped_file.html.

While I have been away from Boost, the Interprocess library has been 
accepted, providing sophisticated support for shared memory and memory 
mapped files. I am planning to write devices to access the functionality 
of the Boost.Interprocess for 1.36.

Currently there are no devices for TCP/IP communications. I am planning 
to implement blocking TCP/IO devices using asio for 1.36, but I also 
hope at some point to achieve a better degree of integration. Standard 
iostreams are not a very good way to access network connections, since 
they are designed for blocking i/o; however, Boost.Iostreams is also 
intended as a framework for filtering, and I was careful to design 
filter concepts that would work with asynchronous and non-blocking devices.

When Boost.Asio was proposed, I was looking forward to the possibility 
of introducing asynchronous and non-blocking device concepts to make the 
libraries work together, but unfortunately I became so busy that I was 
not able to participate in the review process or collaborate with Chris 
Kohlhoff in the subsequent development of the library.

Now that I have more time I am committed to trying to make the two 
libraries work together as much as possible.
