Seam definitely lets the user have two conversations open at the same time
with the same user session, but multiple browser windows. This would
allow you to have two separate instances of the view.

scoping functionality, but does not have the capability to do multiple
instances of the same view.
I wonder if any other have had the need to launch two instances of the
same root view.
