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.
