I've been thinking about this lately, and the only issue I can think of relates
to shared devices. 

In the case of the staff interface, you can have shared circ terminals,
although it's probably not a drama.

I'm thinking more about public OPAC terminals at libraries. If a user closes
the browser, I don't think the local storage gets cleared. HTML5 session
storage might work although I think its scoping differs a fair bit from session
cookies. 

I suppose it'll differ on a case by case basis...

Anyway, I think it would be interesting to take advantage of local storage and
session storage more often for sure.
