Ajaxify File Upload and add progress bar

Any thoughts, preferences, suggestions on what ajax helper framework to use for this? I may have the chance to do something at my paying gig very similar to this, and would just as soon do it in the same technology so it would be easier for me to write the code for AppFuse or maybe simply contribute it back.

If there is something available in one of the frameworks already included in AppFuse that would be good to (re)use.

I just found this... looks to use all stuff that is already in AppFuse.... may be worth a look.
