If the phone can boot off a thumb-drive then people could have a keychain thumb-drive that serves the sole purpose of a minimal OS that can iPXE, boot the real OS and pull down the users contacts, apps, etc... maybe?

Without a verified boot chain, security would be greatly compromised.

Like I could just grab your thumb drive, and put a new system on there that looks the same, and steals your password.
