While dsh or Ansible ad-hoc commands would report back the output,
Ansible won't work for / isn't designed for interactive use and it
would be quite awkward in dsh too. Wouldn't work for full terminal
applications and the like. So config management, ssh multilaunchers
and shell loops aren't the right topol for this.
If all you want to do is launch the same command everywhere, it's
pretty simple in tmux. Get all your logins in different panels and
then synchronize them so the same command is launched in all. Then
unsync to go through and interact individually again.

Basically you are wanting a scriptable full terminal, so tmux fits
the bill I think. You can remote control it from outside in many
ways to get it to do what you want.
