What I'm trying to do is basically this:
- start byobu in the foreground when the script runs
- have the rest of the script run in the background and use byobu cmdline syntax to pass commands and keystrokes to the byobu instance in the foreground.
I have an existing fairly contrived script that does a bunch of stuff with screen splits and keystroke injection but the part I can't figure out is "How to launch byobu up front, so the user can watch it all happen from behind the proverbial bulletproof glass"
