Well, I don´t think you can ever get a response from such manufacturer...I did contact Pioneer right after I decided to buy N9 as I knew this app and saw it in action on iPhone 4, I was unfortunately told that there are no plans to release such app for any Linux-based devices...iOS + Droid got it all lined up...sadly, no space for another platforms with such apps...
But if there´s a guy who was able to make a similar app, which actually works on Droid, on his own, I hoped there could be someone capable enough to make it work on N9, too...
