Thanks for posting, as this question has been also puzzling me for a few days as I work on my own Web Apps-related actions. I found this very helpful in motivating my thinking.

I have attempted to describe three interaction examples that may or may not exhibit properties of Web apps architectural additions at (related also to ACTION-355, Tracker) I hope that these may be helpful in our related discussions. 

I go back and forth on whether these examples truly describe anything new, but if they do, one item is perhaps the notion that a "client" may expose a resource (its location, for example) to the Web in a non-traditional way (via a call to a Javascript API, rather than by acting itself as an HTTP server). Architecturally-speaking, I am not still sure what else is really different from what is already in AWWW -- rather than simply additions to that architecture which were always available, and sometimes used, but not described in any detail.
