The problem with the Lytro was that the sensor/lens pair was just too darned small. If they had somehow scaled it up so that the sensor was about 4" in diameter, even if it meant using an interposing frosted glass plate or something to allow a smaller image sensor, the depth of field effects could have been fantastic. It would have allowed genuine and beautiful bokeh across almost any arbitrary focal plane, even pan/tilt, in software.
