The answer is no. The player source code is heavily used in other products (e.g. the Rio Receiver, or the HSX-109). These are still shipping.

It's also being used in several internal demo products, some of which we're hoping will reach production. These are the OEM deals that we're actively pursuing.

The player software is what (to my mind) differentiates the car player from every other MP3 player available. It'll differentiate the OEM stuff from every other MP3 player available. We'll continue to use it for future home products. It'll differentiate them from every other MP3 player as well.

We're not about to hand it to our competitors -- if they want it, they'll have to license it.

This is why we're not planning to open-source the car player software ever.
