Please read what Ricardo said: this is a _first_ approximation, not a final solution. Given what they're hoping to achieve, I'm fine with doing a simple implementation of sessions first, then progressively refining it. Furthermore, there should be nothing conceptually in his design that prevents you from adapting it to other transports: it is basically just preallocating a buffer, then using that as a receive buffer when you find that you have a callback request.
