Yep! That is the plan, to add both a stock list of "system defined"
actions, and also allow the user to define what happens when an event
occurs in a richer, more custom model.

Yes, for sure. The user defined action (As in do something via a script,
executable, something else) is a tricky concept. Questions like, do we
have security concerns? Should we allow further scripting (perhaps even
via jython to do some further core based actions)? How do we abstract
(As you well point out, from the guru mode to the basic and restricted
stuff)?. These are some of the questions facing us in the six month
time-frame. So input is great here, as it is still up for discussion in
these areas. Any opinion or input is welcome.

Thanks for the input. I love to see it, and welcome any further thoughts
on the line; post them to the list if you have anything else on the
subject.

Many Regards
