There's one other possibility also that doesn't involve changing the client: User installing a transparent local POP3 proxy that talks regular old POP3 (or IMAP) to the client but an extended protocol to the remote server. Of course there wouldn't be a whole lot of users doing this, but it's a possibility for some motivated ones.
