I've created a simulation framework called simbit to simulate the selfish mining attack, though it is general enough to simulate any p2p network. I even put together a rough simulation of MinCen. The goal is to be fun/easy to rapidly prototype protocols and strategies, and visualize them. It's

Once the ASIC race calms down because everyone has one, has more or less optimal power supplies, process improvements aren't easily reachable anymore etc then I'd expect people to dissipate from the large pools because eliminating their fees will become the next lowest hanging fruit to squeeze out

I might try building this sometime soon. I think it may also serve an educational purpose when trying to understand the whole network's behaviour. What level of accuracy are we looking for though? Obviously we need to fully emulate the steps of the network protocol, and we need to be able to

What I want is configurable 1/10/100 millisecond ticks, and accurate flow of information. It doesn't seem necessary to really emulate the whole protocol, nor to be overly concerned with the content of messages, nor to simulate every little housekeeping step or network message. I'm not
