iPod - The missing tools

So, after some time wiht my iPod I must say it is nearly good, a few things are missing:

• a key combination on the remote control to set the playlist to the album of the currently played back song… would be nice, because I use random play over all songs most of the time
• some kind of bluetooth interface, to mute the iPod if the phone rings, or even more sophisticated: to mute the iPod if some friend (look at my FOAF file…) comes in range
• some plugin that reads the interpret and title of the song to me if i request it via a key combination on the remote control

I guess most of the things are possible, but heavily related to extending the software on the iPod… where is the iPod SDK??
