  I'm traveling right now but I will try to add more detail later.  
Effectively we need a way to reconstruct user actions.  This mostly means 
finishing the object streaming in view objects and adding to data objects 
too.  Then we need a fixed size queue and a definition of "actions" that the 
user has done.  We queue objects that can be used to reconstruct or 
deconstruct these actions.  In order to sanely reconstruct actions on view 
objects without reimplementing the code everywhere, we need to be able to 
stream their exact binary representation I think.
