Peter Nelson made an interface to spell(1) that showed putative errors in
context. I believe it could suggest corrections. I remember the project; I
installed hooks for it in spell(1). I don't remember the date, but it would
probably not have been early enough for you to have used it in Columbus.

If there's a chance that Peter's program is the one you remember
and you'd like to get in touch with him, I can give you his
email address.
