I have not looked at Dojo yet, though they have been on "the list" for
awhile.
The firefox extensions are now looking really exciting. I am looking to
download or write an extension that will let me ship photographs from a
camera directly to the database, and also to intercept bar code scans
and do some intelligent page routing. Fun stuff.

Personally ... I think even broader ideas like Dojo Offline
(http://dojotoolkit.org/offline) and Google Gears
(http://gears.google.com/) takes it to an even further level which has
not been tapped (yet). Now if only you can sneak it into a project ;-)

One thing that seems to have gone unsaid in the praise for Ajax is
its ability to radically transform how we maintain state.
The web server session is our basic mechanism for storing information
between requests. But it gets clumsier and clumsier to try to
maintain complex state across many page requests when you use a
session. Ingenious minds have put their will to the problem and come
up with workable systems, but all of them are complicated because of
the nature of the problem.
That problem, stated here, is simply the problem of tracking what
I'll call the "context" of a user's session. Some elements of a
session are fixed: the user id, the password, a few other things, but
almost everything that we need to track is always changing. A basic
example: a list of search results. Where do you store it? When the
user hits, "NEXT PAGE", how do you know what to do? If you are using
a session, what happens if he opens a new window and has two search
results sets up for two different tables?
Ajax solves this problem neatly by letting you move all state [1]
into the browser. This makes sense from an architectural viewpoint
because we are putting this context information close to where it is
needed, the UI.
I've been converting the basic Andromeda UI code over to a completely
AJAX system [1], and have found my code radically simplified and far
smoother, due almost entirely to the moving of all state information
to the browser. Hurray for Ajax!
[1] Here I'll use "state" to mean the changing context of user
requests, and assume we are still using the session for User_id and
password.
[2] Andromeda is used to make database applications for businesses,
we don't care in this case about google following our links.
