I do love good news :-). XTI is the POSIX version of TLI ( Transport Layer 
Interface ). The SVR4 alternative to sockets. Its implemented in Sys V streams 
which means that you can build a custom protocol stacks by pushing and poping 
protocols without re-booting the box, very much like a pipe. Even Windows has 
Sys V streams and I think TLI. And it will be a lot easier to implement a 
networking library on this than on Windows!

One og the reasons I was calling this the network library is that I had in 
mind the possibliity of an XTI/TLI implementation. Possibly using a 
templatised bridge pattern.
