Simulations of an actual hybrid network would be nice. Although as Oskar has pointed out, I'm not sure how much we can actually do in that direction; there are an awful lot of variables, and a lot of them are very arguable. If it's reasonably easy to do, simulating various darknet/opennet hybrids would be helpful. It is useful to know that location swapping and destination sampling appear to be compatible.
I'd definitely want to sort out load limiting before deploying opennet; there may be significant differences for opennet. (Certainly mrogers seems to take that view). Apart from the obvious caveat that we need to sort out load limiting/balancing before diving in to the next Hard Problem, opennet. (Just on the basis of minimizing chaos).
