That for a moment sounded scary as if sched wouldn't be considered
important. I just finished initial version of a Zconvey plugin. It
integrates multiple Zsh sessions and will serve as a base for other
plugin that will make all this semi-graphical. I use sched to pull a
flock-guarded text file, to see if there are commands to run. You said
Zle isn't thought to be working with Sched but the miraculous ioctl(
0, TIOCSTI, c ); saved me totally, everything works, I can update
command line from Sched:

Maybe Sched could be revisited a little and pulled up to work with
Zle, .kill-buffer at least?
