The reason it's difficult to do this and still keep functions 1 and 2 is
that quite often, registrars for the various TLD's display totally
different output. Function 2 isn't actually doing any processing, it's
simply outputting the server response. The only way to accomplish 3 with
just the whois protocol, for all TLD's, would be to know ahead of time the
format for every registrar being used in the search, which would suck to
write. You could make assumptions, for example, key in on phrases like
"not available", "already taken", "no match for", etc. But it's
guesswork, and wouldn't be useful on a production site.
