The P3P Policy (http://www.w3.org/P3P/) does provide some information 
about what data is being stored in the cookies and how it's used. 
Several user-agents (IE6.0/7.0 atleast)  already provide visual 
indicators about these and also provide ways for the user's to 
accept/deny cookies automatically (without showing cookie information in 
annoying popups).

With the new Web2.0 applications (most of them sending requests 
asynchronously), the progress indicator doesn't anymore mean that the 
page is still loading. It's just some data the web site/app is trying to 
load to provide better user-experience to the user.

Some mentioned on the call today that the back ( & forward) buttons 
provide this info. I don't think that's always true. They only display 
the url (page title if available) if the request returns a HTTP response 
status code 200. If the response code is 302/301 for example - the most 
commonly used mechanism to redirect a user-agent from one url to 
another, the original Page/Url requested is no longer stored in the 
browser's history - and hence not displayed in the back/forward button list.

Today all user-agents, with their default settings (which most users 
disable anyway), only display warnings to the user when the redirects 
are from Secure (SSL) to insecure (non-ssl) urls and vice versa. But 
there are no such warnings when a user is being redirected automatically 
from one site (domain) to another. Not sure if it really helps or not in 
all cases but might be helpful against url spoofing.

In the federated single sign on use cases, where users are redirected 
from one site to another for authentication and single sign on, this 
might be useful for the user to identify his own Identity Provider.
