Actually, that was my point about Lytro's embedded viewer technology.  The
desktop app and web app both share the same light field image information.
 And hence they can both theoretically generate 3D stereoscopic pairs.  I
just do not know how far along Lytro is with their viewer software
enhancements for 3D stereoscopic pairs, so you might need to check with
them.  Read their specific blog post here:
