(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.)
