Jon Udell: Rewriting the enriched web

Bingo. Jon Udell's been joining the dots. He's made the connection between Silverlight's script-accessible object model and Javascript. In fact, he ratchets it up a notch - Greasemonkey scripts modifying Silverlight controls on a 3rd party site. That's really very powerful.

Is it actually Silverlight's secret weapon? Well, maybe not. Adobe has the Flex-Ajax Bridge, which exposes Flex and swf ActionScript to a hosting web page's Javascript. It's not as deeply integrated as in Silverlight, where it seems more of a philosophy than an implementation/component (and it looks like it's still a beta).

So, perhaps this isn't Silverlight's unique selling point, but I still think this is a great development model, and Silverlight may well prove the tipping point for this kind of design.
