Was taken at f/3.2 so there is no reason you couldn't get this shot with a f/2 shot from a plenoptic camera with a 35mm lens and a APS-C sized sensor (you would actually have to use some of their software to increase the depth of field to get that picture).
Lytro doesn't give specs on the focal length or sensor size; I think we can assume it's probably closer to a point-and-shoot than an SLR, and everybody already knows it's hard to do shallow depth of field with a point-and-shoot, it's not anything specific to Lytro's camera. The majority of point-and-shoots have a fixed aperture (if you "stop-down" for outdoors shooting they just use an NDF filter).
If they come out with an pro-quality exchangable lens large-sensor plenoptic, you ought to be able to do the same sorts of things you can do with a pro-quality non-plenoptic camera, only you'll be able to do it e.g. with moving subjects that you otherwise would not be able to focus on with such a narrow depth of field (and as a sacrifice you would have many fewer pixels).
