Boost.Asio currently supports only network I/O out of the box. However it  
can be extended to support any asynchronous I/O operations. For example I  
have created a file monitor which I can plug into a Boost.Asio I/O core  
service. If a file changes then a handler is called. Thus it's the same  
concept as used by the network services (which are really the only  
services provided by Boost.Asio today and which made me also wonder some  
time ago why this library isn't simply called Boost.Net).
