Re: Is this port forwarding or something else

All these machinations are coming up because I can't think of a way to
automate rsnaphsot backups between rhost1 and rhost2 without having to
login on rhost1 to either run the command or start the ssh-agent and
add the necessary key with ssh-add so a cron job can access the
socket.

Why not:

run ssh-agent on your local machine, and add a key there.

ssh into rhost1, using agent forwarding.
from there, run the remote command on rhost2

I guess it wasn't clear in OP that I want this automated.

I have user privs on rhost1 and rhost2 but root on localhost.

This does depend on agent-forwarding being allowed by sshd on rhost1.

All subject hosts allow it.

Another possibility is to use host-based authentication between
rhost1 and rhost2. That's what I plan to do if I ever get around to
automating my backups. This depends on sshd allowing host-based.

What do you mean above? Is it something that requres root on remotes?
Is it something you setup once and it can run unattended (from cron).
