New Universal Widget API from Netvibes

The promise of a write-once run anywhere widget API has grown potentially more interesting with the release of the UWA from Netvibes. Here's an excerpt from the site:
The UWA relies on a soon-to-be-released open-source JavaScript runtime. Through JavaScript best practices, our components and templates, the UWA makes it easy to assemble a widget for any given web service. Since our primary announcement, some great platforms contacted us to collaborate on expanding the reach of UWA widgets.
