The discussion which I have been having with Jiri was trying to come up with a rough draft specification of how to do synchronisation between modules. That 'document' includes a brief summary of what a Petri Net is.
I would like to try and come to a consensus with Jiri before posting it on the list, because I was afraid that too many partial ideas and opinions could arise, and the whole thing would grind to a halt.
Right now I think we have nailed down practically everything (with one exception which I think we need the list to decide between two options - to use or not to use callbacks - the specification should make it clearer what its all
about). Like Jiri said, I am just waiting for him to have time to review the current status of the 'spec'.
Mario.
