Anyone know of a bluetooth controller for Zune?

I’m looking for a Bluetooth controller for the Zune.  I know I can get a Bluetooth adapter that just plugs into the headphone jack, but I’m looking for one that can actually control the Zune.  For example here is something similiar that works the iPod http://eleksen.com/?page=products/controlelectronics/ce_bluetoothcontrollers.asp. 

Given that the Zune dock and remote control is out there I know that the device can be controlled via the connection on the bottom. I don’t even need the connectability of the adapter and the mobile phone like the one above.  The motorola BT headphones I have already do that…I just need the ability to listen to the Zune over Bluetooth AND control the Zune via that same Bluetooth signal for stop, play, forward, etc.
