Well we had what I think is the first BeagleBone Black to BeagleBone Black Allstar QSO tonight when KB4FXC and I connected. The really cool thing is that he was running usbradio on his end!!!  Yes, usbradio on the BBB!  I was running simpleusb on my end.  He reported about 20% CPU utilization and I was at about half that.  Good audio and no delay. Very exciting.
