... and a lot more load on the CPU.  Same-machine "network" connections
are much cheaper (on most kernels, anyway) than real network
connections.

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.
