If a collection is smart enough to "know" the search arbiters in scope,
shouldn't it also be smart enough to act as search arbiter itself (just
forwarding the queries to actual software modules)?

Just because it's live doesn't mean it can't be changed/modified... Seems
that this topic needs more discussion...
