If anyone can forecast the development curve of

it is easy to engineer address space allocation and assignment procedures that produce good or even optimal results. Unfortunately there is no consensus about these developments and the more wise people do not even try to speculate. Therefore I would like to keep options open as long as possible and also use a scheme with lots of flexibility.
Amen. People sometimes naively and innocently ask "When will the next version of <insert any interesting protocol> be deployed?", believing things are actually planned and orchestrated in great detail in advance. I always reply "Just before it's too late.". That's the track record so far, and nothing suggests this will change. Currently that "too late" is in the next century, so anything devised here and now can only be experimental, for educational use. Cast it in stone and it will float like a rock. -- ------ ___ --- Per G.
