After reading about the drawbacks of deterministic wallets from http://bitcoinmagazine.com/8396/deterministic-wallets-advantages-flaw/, it seems to me like Armory's watch-only wallets (and offline wallets as well, actually) have the "master public key" mentioned in the article, easily obtainable.

Does this mean I should never reveal any of the private keys of my deterministic Armory wallet? If I did, I would risk compromising all the private keys when someone gets hold of both, the master public key and any single private key of my wallet.

Someone, please verify!
