RIA state transparency

interesting post over at udell's:

...The idea that an application wears its state information on its sleeve, readily available for users to bookmark, modify, and trade, is an underappreciated strength of Web-based software. As the RIA bandwagon picks up steam, let's honor that idea and find a way to move it forward.
[...]
The web's architecture is compositional. When you expose application state on the URL-line, to the maximum degree possible, users and developers become co-composers.

Flash needs to figure out how to enable this collaboration, fundamentally and pervasively. Likewise DHTML. Likewise Java, .NET, and all the first-generation GUIs.
