Yes, some of them can easily be changed to use DynamicVariable (if the 
communication direction is bottom to top and no lazy initialization 
is involved), but others are a bit tedious to implement this way. I think 
the best solution would be to separate these communication exceptions from 
Notification by creating a new subclass of Exception for them.
