Hi Fletch,
I made this mov file with the cubicpanoout > GoCubic workflow and it was fairly easy to do but its a straight SU output.
cubicpanoout can however create the scenes as mirjman suggests above and you can later render them in Kerky (I think using the spherical camera as I was told by Frederik) and stitch them together with GoCubic.
AFAIK this is how Martin made this panorama as well.
