>From a practical point of view you need to define "edit" somehow - the obvious answer is changesets but that can be easily gamed so it will presumably need to be the number of objects added/changed/deleted.

Doing it per day is probably excessively expensive from an implementation standpoint because it requires resetting counters at some point, or keeping say hourly counts and expiring those over a day old. A token bucket type algorithm like the download limit probably makes more sense.

>From a personal point of view I dread dealing with the resulting complaints...
