Sounds interesting. At the moment we don't have any plans for Jasmer addons, but I will add your suggestions to our "ideas list".
The pyramid might be easier to implement, although you have be constantly working on it (such as the Jasmer itself). With increasing time it gets harder, though. At some point there might be to few caches for the middle years?
We would have to look into the numbers for the physical one.
I can't promise you anything, but we will consider it.
