Cedric, your original message went through just fine. :)

We're using a module from Roving Networks. I'm not sure which chipset it's 
based on.

By the way, several weeks ago we designed and built a module that's 
pin-compatible with Sparkfun's:

We also threw in a couple of status LEDs. We haven't gone to production yet, 
because we aren't sure how much interest this module will generate. If we 
ever do, the price point will be in the $45-50 range for singles.

Sorry, I can't really comment on this -- I don't have any experience with 
using Bluetooth for audio.
