I'm developing software for the a6300 using the Sony API, for a situation where the rear camera controls will be inaccessible. The software will do things like stream the live view, adjust exposure, snap photos etc, along with other non-camera functions in a single software app.
Ideally I would just power on the camera remotely (this is working via AC-PW20 adapter), and Smart Remote would already be enabled so I can connect over wifi and control the camera. More ideal would be control over USB, but as far as I know only Sony knows how to do that (as they do in their Imaging Edge software).
