Second Audio Stream Output

Hey there,

Wouldn't it be great if there would be the option of playing a second audio stream to a second output? (Which would be used with headphones.)

For me it happens sometimes that I watch a movie with kids, which they need to see in German, but I would much rather see in its original language, English or French.

Or sometimes Friends don't speak a language well enough to follow a movie. In this case, subtitles are an option, but a second audio stream on headphones would be sensational!

Anyway, would like to hear what you think about it!
