I think all of this discussion is vast overkill. No one has yet
demonstrated that it's not sufficient to have *one* collector process
and a lossy transmission method. Let's try that first, and if it really
proves to be unworkable then we can get out the lily-gilding equipment.
But there is tons more stuff to do before we have useful stats at all,
and I don't think that this aspect is the most critical part of the
problem.
