This is assuming you want something that will work for any TLD. For a
single given TLD, the whois output should be consistent enough that
you could figure out something to determine if a domain is registered
or not.

For instance, for the .ca domain it looks like just checking the first
output line for "Not found:" is sufficient to indicate a domain hasn't
been registered.
