It seems like it's been mentioned on here before, that a number of "two
factor" or "multi factor" authentication schemes actually use a cookie
as the second factor.

Anyone here have specific experience with such solutions, or opinions
about how much security they add to a system?

Cookies rely on DNS which is weak.  Not saying you shouldn't do them as
part of a number of risk management techniques, but that is just because
they are so easy to do, just like grabbing the ip address, but it
doesn't really add to security.
