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.
