Hmmm, at first that sounds more like a BGL problem than one for the 
statechart library. What you describe above is easy to do with an 
appropriately designed state machine but I'm not sure it would be the 
right abstraction. For what real-world problem do you plan to use 
Statechart?

Yes, that is probably the feature every FSM library supports.

Yes.
