(Note that I've not examined OpenDNS's offering, so I'm _not_ pretending
to comment on what they do.)
Let's quit looking at overly-simplistic correction mechanisms. Do spell
checkers force autocorrection with only a single choice per misspelled
word?
Return an A RR that points <correction service>-controlled system. Said
system examines HTTP "Host" header, then returns a page listing multiple
possibilities.
"The site you specified does not exist. Here is a list of sites that
you may be trying to access: ..."
I'm generally ignoring other protocols to limit the discussion scope.
However, one can see how SMTP and FTP might be similarly handled. (IMHO
not as good as a SRV-ish system that could return NXDOMAIN per service,
but actually somewhat usable today.)
