Right now I'm not working on any problems that make me interested in actually running Petri net models. I do appreciate all your work reviewing Petri net software and will include a chapter about that in the book (which keeps getting delayed, but I hope to finish this summer). But since I don't tend to use software for computation (just communication), I tend to avoid math problems where software would be useful.

This _might_ be something we could fix by working together, but it would require that both of us decide to do it, and communicate enough to make it happen.

More later...
