Yes, that's the list I was thinking of. The linked discussion was interesting. Good find! Perhaps the GnuPG devs are right that hex finger prints are more internationally viable than English words.
I've been thinking a lot about using words to stand in for numbers (eg: fingerprints) -- and I think the idea is good. But i18n should be considered -- and the PGP world list is probably the worst example I know of. The only thing it has going for it, is that is already collected/created -- but seeing as how it's not implemented by gpg -- that is kind of moot.
I can see why it would be hard to find one set of words that are easy to pronounce/understand in every language and every culture. But perhaps that isn’t necessary? I’m thinking that this feature needn’t be available in every localized version of GnuPG. Or that there could be localized word lists for various languages.
