Yes, that a possible solution (though it will work reliable only if
you only have a single local instance of your app running.) If you add
those TXT records and this is for an "official" protocol, consider
adding a "vendor prefix" to your key
name. i.e. "org.foobar.supersoftware.cookie=". For more information on
vendor prefixes see the dns-sd spec, chapter 6.4.
