Getting iPhone volume

In Objective-C you can do this:

musicPlayer = [[MPMusicPlayerController iPodMusicPlayer]; currentVolume = musicPlayer.volume;

and get the audio volume…

Is there something like this planned for Corona? I noticed that it can’t be done so far.

I need to show a warning to the user that my game will not make sense if the audio is not on (hint: audio-book-like game), otherwise I don’t want to bother them with a warning.
