HDW-2 - Connecting to a PC?

can any1 here tell me if it is possible to use the HDW-2 on my computer?

For example, could i use it with MSN messenger to have voice chat? instead of my mic and speakers?

I have just tried to pair it with my computer, which was successful, but my HDW-2 just keeps making a funny tune.

it would be so cool if that was possible, is it anything to do with creating a serial port? (im not to cleber with BT....dont understand it fully)

When i sync my phone with outlook, it creates a serial BT port.....thats all i know.

Thank for any help
