If the Code Wizards at Rode can implement the diversity of options present in Unify without significantly affecting latency, even if it means plugging both USB cords into the same PC, then I can't imagine why there would be a streamer out there who'd pick a GoXLR over the RCP2 unless they absolutely require the bonus blinkenlights.
(Maybe drop a hint to the Code Wizards about figuring out a clever way to hook USB devices, I'm sure I'm not the only one with a wireless headset and soundbar that are about to get very, very dusty. That and I really want to keep my old NT-USB around as the Little Brother mic.)
