CI has a couple of tested FW800 hubs, my interest is the integrated solution, with the ability to add a battery pack. It's more because Hasselblad really dropped the ball with the ImageBank and all the H3/H4 users. Given how much battery tech has evolved and the removal of FW from Apple laptops, it would be nice for anyone shooting a non-current back, generally designed around FW400/FW800 to have a battery powered tethering solution.
