See responses below. I cut out text that I didn’t need to respond to.

You can load-split by using several sets of anycast map-resolvers. So you have 
two levels of spread.

But you require it in all LISP nodes.

Do you agree the draft-rodrigueznatal-lisp-pubsub-00 is a simpler and more 
effective way to introduce pubsub functionality.

FYI for others on the list, we have asked Med and Christian to be co-authors on 
draft-rodrigueznatal-lisp-pubsub-00. It would be good for you two to deploy 
pubsub to verify the design.

Do you have time to do this? There should be two implementations available soon.
