I have a variable, lets call it foo, that may change from time to 
time. When it changes I want certain of what one might call subscribing objects 
to be notified that the variable has changed. This gives these objects the 
ability to update themselves or take necessary actions. I am thinking 
this could be tied into the binding mechanism since this is a subset of what 
binding does.Any insight greatly appreciated.Hank
