Client-API for  Monitoring Download Progress of large amounts of data
---------------------------------------------------------------------

                 Key: JBSEAM-855
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-855
             Project: JBoss Seam
          Issue Type: Feature Request
          Components: Remoting
            Reporter: Stefan Frank
         Assigned To: Shane Bryzak
            Priority: Optional


If you transport larger chunks of data via remoting, it is currently not possible to monitor the download progress. The effect is, that you can only display an unqualified busy-animation to the user.

We implement this manually right now, by breaking down the date into smaller chunks and then reporting back the progress based on the downloaded chunks vs. the total number. of chunks. 

An enhancement would be to have:
 - a possibility to register a callback for progres on the client
 - a feature to have the data(especially collections) chopped up automatically  and sent in smaller chunks (maybe some annotations as hint?!)

This would make it possible to display a proper progress-bar on the client and report back, that the download is still running.
