Sixaxis and DS4 touchpad support? Not sure how to use touchpad, but at least make it available to SDK.
If you can get the input on PC, e.g. through third party DS4 drivers, then we'll pass it through, but having it appear to the PS4 as a DS4 touchpad is up to the XIM4 itself, and as you know, there are issues with sending touchpad comms to the PS4 from anything but the official controller. No one seems to know what the deal is there.
Xbone chat audio passthrough? It would be awesome if i would be able to use XIM for chat passthough instead of horrible pile of cables and adapters to pc. (I dont chat on xbone, but if i would this would be great).
I'm not sure how much access we have to the encoded audio stream, but it's definitely something I'd be willing to investigate. It would need audio-injection support in the firmware, which would require OBs and/or Orbital to do stuff, since I won't have the firmware code myself. There are also potential issues with bandwidth over the transfer cable. This might have to be a stretch goal.
Thanks, good points, and I added them to the original post.
