It's still unclear to me what problem are you trying to solve. Can you
describe the motivation and then describe the full commandlines you
issue?
If it's for notification only, why not use either some desktop
notification software or just put the notification message into tmux's
status bar?

Yeah, each pane in tmux will have its own tty device.

Yes, use something like "tmux list-panes -a -F '#{pane_tty}'". You can
look up the arguments and more formatting options in tmux's man page.
