Hi Jarl!  Sorry for taking a while to get back to this.

What do you mean by "a new PL"?

Can you give me an example of a pushed response?

I was thinking about a node that would work as an interactive tty/console,
perhaps running Peep or bash.

Are you talking about text that the UI and DL would not "expect", text that is
only for the user and not to be passed on?

Couldn't we put a "text viewer" in the pipeline of whatever application to do
