Tabs on the same browser have the same set of cookies, which means
they have the same session (at least that's my observation in IE).

If you ask really, really nice (with huge trainloads of money),
Microsoft might change this in Service Pack 86 of IE. But I doubt
it. Or you might find a registry key you can tweak to get that
behavior: on your browser only.
Note that giving each tab their own bucket of cookies probably means
that every new tab is logged out of everything, and that might break
the way some existing sites work (anything that (a) opens a new tab
and (b) requires you to be logged in to view the new tab would
likely break). Functions like "remember my login" would only work
on individual tabs. Is that really how it should work?

Referer won't tell you what tab something came from. It's also trivially
easy to fake.

Switch browsers? I think there's a browser that DOES give a different
bucket of cookies to each tab. Opera perhaps?
