Apache Pivot, Platform for building Rich Internet Appplications

Apache Pivot is a framework for building Rich Internet Applications. Pivot seems to have taken inspiration from Flex and Silverlight.

Here is a snippet of overview from Pivot website,

"Pivot applications are written using a combination of Java and XML and can be run either as an applet or as a standalone (optionally offline) desktop application. Pivot includes features that make building modern GUI applications much easier, including declarative UI, data binding, effects and transitions, and web services integration." 

I would personally choose Pivot over Flex or Silverlight as it is easier to integrate builds into Continuous Integration and Maven. Not sure where Pivot will head to but it surely seems a promising technology.
