[Dev] Notification Manager using Item Queries

[Brian Kirsch]

Hello,
After giving it some thought, I am starting to think that perhaps 
leveraging item queries as a replacement for the Notification Manager 
is not the best solution.

Technically I think it is possible to use item queries to deliver 
notifications across views / threads. My concern is with repository 
performance. The additional number of refreshes and commits required to 
propagate notifications across views is gonna add a lot of CPU cycles 
to the Repository Layer.

Going with a more traditional subscribe / notify event model will 
prevent the need for constant commits and refreshes.

Using item queries for notification is a very interesting concept. I am 
open to suggestions on ways around the performance issue.
