[jdev] Announcing Gradient / Scaling between federated servers

I would suggest no doing it like this, as far as I can see you would be far
better of using pubsub for whiteboarding like this as others have already
been discussing, either on JDEV or Standards-JIG, have a look in the mail
list history.
