Some questions about audio on embedded systems

Hi,

 I'm doing some research for an upcoming project where I'll need to use 
a bluetooth headset for audio (send & recv) with a gumstix. I found the 
following two pages:

http://bluetooth-alsa.sourceforge.net/embed.html
http://bluetooth-alsa.sourceforge.net/embedv1.html

which have great information, but I'm curious as to which is the most 
current/correct. Specifically, I'm wondering what the current status of 
SCO audio with the gumstix (and just on regular PCs frankly) is. I 
understand that the blues-alsa project is moving away from btsco toward 
plugz, but didn't know how this would affect me on a gumstix.

Any info would be greatly appreciated.

Thanks,

-d
