I'm not talking about telling the laptop that it's access is revoked; I'm talking about just revoking it's access, so if it every tries to connect to the House's intranet, it would have no more permissions than any other laptop. If IT wanted to wipe the drive, then they would need the laptop to phone home in some way.
