OK, here's something I haven't seen mentioned yet. I tried testing a Cardo Scala 500 bluetooth headset with just the Mac. Seems to work great, I am able to set the default audio I/O to go through the headset with just OS X. Now, with Parallels, I seem to be getting the audio output just fine. All the little windows noises are right in my ear. But the input from the mic does not get passed into PWS. Not sure if this has been documented before, but thought I would add it to the list. Thanks for all the great work!
