The docs on the web page say it's possible to use asio with no boost
libraries, and without OpenSSL. Whether that's true in practice we'd
have to see.

Reading the design docs, this looks like it would help solve some of
the problems in the mtn netxx_pipe class. The current netxx design
doesn't allow overriding netxx operations; apparently asio does allow
that. 

Also, it says it has an implementation of async IO on Win32; that
would fix the problems with sync file: and ssh: on Win32.

The downside is that the code is all hairy C++ templates; it could be
very hard to understand and debug.
