[Paul Stevens]

If the 'WAIT' works well then it should be
relatively easy to add a hook to a timer.
Then you could write a script that causes
an automatic 'WAIT' once per second if the
party has not performed some other action
in the previous, say, three seconds.

Now things start to move around as they
do in 'Dungeon Master' or 'Eye of the Beholder'.

I suppose that could be considered heresy.
