TnFOX is a metaprogrammed platform abstraction and GUI layer for my 
next-gen operating system platform, Tn (http://www.nedprod.com/Tn/). 
It was still compiling a few years, but I'd imagine it has a bad case 
of bitrot. Either way, that's all ten year old code and design now, 
and very much an orphan isolate in that it doesn't use Boost or 
recent patterns in C++. It also, rather unhelpfully given the modern 
world, wasn't written with embedded processors in mind and assumed 
exponential growth in CPU clock rates would continue much longer than 
it has.

As it happens, I was recently employed by a major corporation on the 
basis of that next-gen platform design. As a side project I'm busy 
reimplementing parts of it in Boost and C++11 right now, so you /may/ 
see something written using Boost.ASIO and Boost.Graph hit 
Boost.Sandbox this summer with the hope of it eventually being 
accepted into Boost. I'm hoping, if it works out, that said side 
project makes possible many other useful things for C++17 and beyond.

I'd imagine these are highly bitrotted by now.

You may also find a discussion in this list's archives some time ago 
about what we ought to have in Boost.Python v3 (v4?) of use. There we 
discussed the general Python<=>C++ layer implementation, and how it 
would be nice if it could be arbitrarily configurable via invoke 
policies etc.
