Yes, I understand, sorry I wasn't thinking it through.
So what about Windows and Mac OS users who auto-login and are not
required to unlock their keyrings before joining their wifi networks?
Surely Mac OS stores encrypted wifi network passwords in a keychain
rather than in plain text, getting users on the network at login with
