I’m not aware that such would be a possibility, because 1) it wouldn’t work in VorpX the way I imagine this working, and 2) it wouldn’t work because HDMI protection on the PS4 probably would not allow that kind of passthrough. the remote play works awesome, and looks great, so I don’t know why I’d want an alternative approach. If you’re close enough to run an HDMI cable, you’re close enough to run a network cable. Sony has a standalone program for the PC to do the remote play; again, it works great.
Maybe I’m missing the point of your question, though. Sorry! =D
