"ipod-library" is only supported if IOSPlatform is loaded, but it will not be loaded on all platform due to check for HostUtils.isIOS(). Do you know what happens if user tries "resource" protocol on not supported platform? and same for some "unknown" protocol. If error message makes sense we can probably keep it as is.
