PS vita does not even have its Remote play yet...
PS Vita Has PSP emulator that runs the PSP Remote play with the PS3 doing a few tweeks.
The firmware for PS3 Needs a new Upscaler for the Vita resolutions and it has to Detect if the source game is a PSS or PSP or PS3 game then run the correct upscaler.
Its not even ready yet.
Running remote play as it currently stands is rubbish as the vita has to Upscale the PSP feed draining the batteries when the PS3 should be doing the upscale as its on mains..
