I suggest that we allow ratings by anonymous users (IP numbers), at least
in 1.5.
Reasons for this:
* we've always worked by leaving things as open as possible and only
restricting as needed;
* we're explicitly not using the data for anything important yet, so if ten
thousand rating spammers put [[Image:Autofellatio.jpg]] top marks for
everything, it won't actually affect anything;
* the raw data will be of great interest to people, and as wide as possible
is good. (I can see the academics studying Wikipedia slavering for the
ratings data tarball ;-)
