Since I like to do panos of fairly close-up subjects (no room for parallax error), and low ISO work requires a tripod anyway, I made a contraption that is tailored to the nodal point of my C/Y 35-70/3.4. The tripod socket of the NEX cameras (5N and C3 at least) ist pretty much useless anyway, so the lens adapter got a "tripod foot" for rock solid attachment. All in all a fairly compact and lightweight system when you consider the capabilities, though it certainly isn't beautiful by any standard.
Example (@70mm/f4, 3x5 images), this simply wouldn't work offhand (or with any amount of wind, for that matter):
UWA capabilities (@35mm/f11, 3x3 images):
To be honest, my first thought when I saw a NEX camera was that this would make a great "digital back" for a pano system, and I'm amazed that noone has brought anything like this to marked yet. With some technical (and cosmetic...) refinements, this could be used with a variety of lenses and still be a whole lot more compact and lightweight than the common pano systems for DSLRs that are ridiculously bulky (and shaky) by comparison. Additionally, working in landscape orientation is much more convenient than the usual portrait orientation, especially with tilting screen.
