I normally use Spotify, so I've tested it with a number of phones:
T-Mobile GS2 on CM10 - no volume control, only shows "BTA" on the head unit
Galaxy Nexus on stock 4.0, 4.1, or 4.2 - volume control works, will display "STREAMING AUDIO" under "BTA" when BT audio is selected
Galaxy Nexus on CM10, AOKP, SlimROM, LiquidSmooth, Paranoid Android and Bugless Beast - no volume control, only shows "BTA"
VZW GS3 on stock or modified stock ROMs, ICS and JB - volume control works, MIGHT display "STREAMING AUDIO", sometimes it doesn't but volume can still be changed
VZW GS3 on CM10 - no volume control, only shows "BTA"
Nexus 4 on stock 4.2 - volume control works, shows "STREAMING AUDIO", but the phone likes to unpair itself every time I start the car.
I've also tried a couple of these with Rhapsody and Rdio and the head unit responses are the same or similar. In fact, Rhapsody will actually show the artist and song for a split second when it starts playing, then it disappears. Google Music seems to work across the board.
So basically if you want to use any of the decent streaming music apps and want volume control, you'll have to use a stock or stock-based ROM. I don't know if this is the same case for pre-ICS phones/ROMs, though.

I'm wondering if there was been any development on this or if the AOSP/AOKP teams know about it.
I'm currently running CW10 4.1.2 AOKP on my Galaxy s2 i777. As soon as bluetooth connects, I'm allowed 5 seconds to adjust volume. My head unit only displays "BTA". I've only tried this with Double Twist but now I know its a problem with the ROM and not our head units.
Besides the FM/Bluetooth switch for volume control, what I've been doing is setting my bluetooth volume to half on my phone then adjusting it on the head unit to something manageable. I place my phone in the little cubby by the aux and usb slot and adjust volume through my phone.
