Ok, lets clarify, there is a main difference between notification 
agents, and events
Events will be associated to user interface events that a programmer can 
use for execution of custom code. The notification is related to the 
data himself, when data have certain value.

The working model also would be different, the events will only be 
trigged when for example, a new row is inserted, on field update, and 
others. Notification agents would work for the table tracking changes. 
What you think?
