Yes I definitely think that each object must signal when it changes, and 
that the object that owes all information to take the decision should wait 
on these signals.
And to me we should take time to take a deep look at what is done now, and 
try to clean up these signals to make the thing coherent, because anyway 
this will be the base for future features and should be clean. Moreover 
I'm pretty sure we're signalling the same thing several times and loose 
efficiency here and there.
