I envision 2 parallel networks, the new one authenticated for sending spots,
but not receiving. The legacy network remains as is, but hopefully has hooks
in it to feed the new network, and likewise in return.
The new, authenticated network is like airport security: once through the gate,
you can go anywhere (ie post and receive spots). You can leave at any time
(receive spots only).

Yes, an enhanced messaging format should be required at least among cluster
servers. It's important that cluster clients need to make no changes if at all
possible.

With proper authentication, garbage in will be easy to follow back to the
origin.

Who maintains AR Cluster now ? I keep hitting dead ends.
