Can I use my Android phone as a bluetooth microphone (for Skype)? I do some international phone-calls. Gets annoyingly expensive. I didn't like a bigger Android mobile, so I got this small Motorola Fuzzout thingy.

Is there any way to link the Android phone as a Bluetooth microphone? I can run Skype on my Mac or Windows PC. However I'm not sure how to connect the devices that way.
Is the Skype app available in your view of the Market?  If so, why not just make the call on the device itself (via Skype)?
