Very feasible, in much the same way as the current $WATCH system, and I
for one would find it useful. Perhaps you'd like to write it as a module?
All the necessary hooks already exist -- look at the sched module to
see how it runs code before each prompt. (Of course, it could be done
in user code, using $PERIODIC, but that's a rather messy mechanism and
not entirely appropriate.)
(I would implement this tonight, but I'm very busy with real life
right now.)
