Users would have to *want* to use (and separate) multiple personas, based on context, and experience tells us that icons don't generate that desire (cf. the SSL 'padlock'...).

I agree: there are many things to do to improve the value of such features.

The SSL padlock is a good example, of too little value making something relatively uninteresting. The padlock was there to signal to the user that he was connected to a site in an encrypted manner. It was not to tell the user what his own identity was.

In any case it had a number of problems:

 1. It did not say anything about the site or how trustworthy it was
 2. It was hidden at the bottom of the browser, instead of being close to the URL bar, which is where most browsers have it now.

If you look at Aza Raskin's UI solution

    http://www.azarask.in/blog/post/identity-in-the-browser-firefox/

 you will see that what he does is bring the two together, making it easier for the user to see the parallel between user and server identity/security. By tying additional functionality together, such as for example the ability to log out from a site, or change identity, by making the feature more important and more useful, you make it something people pay attention to more.

On server side identity btw, WebID can also be applied longer term to increase trust by building what I call a distributed web of institutional trust. I expanded on these possibilities earlier this year at the European Identity Conference in Switzerland in a talk entitled "WebID and eCommerce"

When you go to a bank, it is important to know that this is a bank you have reached and not some fake. Furthermore it is important to know that it is a bank you can do business with. There are things here that can be moved into the chrome and thereby hugely increase security and trust on the web.

Aza seems to be saying here "you are logged-in to this site as GuyFawkes".  These are different statements, and the first has questionnable value.  Sorry if I misunderstood.
