Apple to allow others to see when auto correct has been used?

Textual ambiguity may be a thing of the past if Apple adopts one of its newly-published patent applications, a system which will inform the person on the other end of the line when autocorrect has been at work.

The method described would highlight any words that were changed by auto correct.  Apple currently does this for the sender (while using dictation), but not for the person on the other end.

What do you think?  Could this be useful?
