It may make sense to define it per view, perhaps like this:

      "limit":"function(userCtx) { ... }"

The suggestion here is that the 'limit' function takes a userCtx and returns
a set of allowed key ranges for this view.

But it may be better to take the actual query as a parameter, and turn the
keys into their prefixed form.  If this were done server-side then the
client would be unable to construct any query which accessed key ranges they
didn't have rights to, so there's no need to do any intersection. It would
make the client code simpler too.
