You could use tmux(1) and launch many windows (not panes) each with an
SSH session. Then you could script something and run it in the first
(0th) window:

while read -p "cmd: " cmd;
do
        tmux list-windows \
        | awk -F: '{print $1}' \
        | tail +2 \
        | xargs -I{} tmux send-keys -t :{} "$cmd" C-m \;
done

Or if there are only a few sessions, you could make multiple panes in a
single window and use 'synchronize-panes'
