Yeah, I was actually thinking more along the lines of 'screen' when I
trailed off - but I haven't played with it much.  Consider: split the
terminal into two panes, one 24 or so lines, and the other a 1-line
"status bar".  The program running in the status bar pane would display
some pertinent information, say, date/time, how much new mail you have,
disk free space, mbmon stats, whatever.  (One thing I always wanted was
a progress bar for long 'make' jobs...)

That status bar program could poll other programs and reformat their
output to produce its display - but polling is just damned inelegant.
It would be so much nicer for it to be event-oriented somehow - to
receive messages whenever state that it's interested in changes.

Anyway, at this point I'm just rambling.
