I'll definitely give this a try, but if it's anything like the Vita's Remote Play software it will be plagued with lag, video glitches and random disconnects. It's a pity Sony didn't bake this capability into the hardware like Nintendo did with the Wii U as that has always worked perfectly (albeit with the range limitation of the GamePad).
I do like to think that the Mac's wireless capabilities are head over heels better than the Vita's, though. But since it's still probably bouncing through Sony's servers, who knows
