What you are asking for here is:
        http://chorus.sourceforge.net/
... in my slightly biased opinion. ;-)

This gives you a stackable transport framework which includes (among other
things) a multiplexed channel.

This project is still really new, but is shaping up nicely.

However, it has no relation to boost and is primarily targetted at building
distributed hash tables (p2p apps) that can go through any data channel.
