Yes, you would need to buy the Bluetooth dongle sold here on the store. Chuck can give more details about why this is.
so since im running parallels, im running XP. My mac already comes with bluetooth capability. I use it to connect to the internet on the road. so if i used streetdeck and wanted to use the cellphone feature, i would have to buy a bluetooth dongle? Seems a little weird.
bluetooth is something that is pretty finicky, and it would be difficult to troubleshoot all the possible driver + hardware + BT phone combinations that people would try to use...
Now, as far as an ETA on the hardware...there's not one that I know of...and there's been no news for a while concerning any development. So, who knows?
