The scenario is as follows:
You have a "system" that is comprised of N servers. This system can change in size both plus and minus (from 1 to 512 - just for kicks) individual servers. These replacements/additions all have unique IP addresses, but have a broadcast response system that can identify "all the other IPs that I need to talk to". ("I" being the server)
Given MY way, I do not need to do ANYTHING except run a bash script that uses MY SSH, logs in to every server, runs whatever I want, and pushes the output back to my terminal. This version of SSH would reside on MY machine, and would be completely compliant with their SSH daemon...
Using keys, I have to at a minimum send a file (the key) to the remote machine before communication, and that may be fine for ME to do in the lab. For someone in the field, (aka NOT me) I don't want to have to explain the details of Passwordless SSH & Keys. Especially to somebody that doesn't want/need to know.
Is this really that bizarre of a concept?

ssh-argv0
SSH-ARGV0(1) BSD General Commands Manual SSH-ARGV0(1)
NAME
ssh-argv0 -- replaces the old ssh command-name as hostname handling
SYNOPSIS
hostname | user@hostname [-l login_name] [command]
hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name]
[-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command]
DESCRIPTION
ssh-argv0 replaces the old ssh command-name as hostname handling. If you link to this script with a hostname then executing the link is
equivalent to having executed ssh with that hostname as an argument. All other arguments are passed to ssh and will be processed normally.
OPTIONS
See ssh(1).
FILES
See ssh(1).
