This is a great idea. Thanks also for linking to John and Jacob's paper [Quantum Techniques for Stochastic Mechanics]( in your running tutorial on stochastic Petri nets. It might be worth summarising a few key concepts in relation at least to underlying structure - motivated by the epidemiology study group. @DavidTanzer, I might have a go at getting started with putting one or two small bits and pieces up on said web in relation to such matters at some point, if that sounds reasonable to you.
