Got mine!  Have them up and running on the same Pi 3B board as 5 2Pacs.  I backed everything down to stock for now to see if the USB bus gets congested, but so far so good.  The 2pacs are all humming along at ~11Gh/s (plugged into a 7-Port Superpbag USB hub), and the pair of pods I got are churning out their ~66Gh/s (plugged directly into the Pi 3B).  One of them is churning out more HW errors than all the others.  Up to 8 of them in about an hour or so, which isn't outrageous.  That aside, so far so good!
