Interesting.  Have you checked that there isn't something available already on 
asio...not sure, but I think someone might have already done something like 
this.  That said, AFAIK it's not in Boost so this would be a nice extension.

Have a look at Boost.Interface

http://www.cdiggins.com/bil.html

This library was never fully proposed for Boost, but it has alot of the same 
ideas/needs as you do w.r.t. binding with C++ interfaces.

Also, a totally different way to go would be to support an IDL like language 
and write a tool to generate the needed C++.

What do you have in mind for the transport protocol?

Thanks!
