From our chat:

for monitoring of nodes
who is catching up and what not

mm, we should probably create/update some existing method to hold this info
net_info
it's bad that you have to use dump_consensus_state for this
you mostly interested in `height`, right?

pubkey, moniker and height basically

We need to create/update some existing RPC method to return node status & the list of peers (pubkey, moniker and height).

oh, man. I love this old school patches thing! It's like sending a paper letter to somebody when you both have emails.
