Getting the Nodal Point exactly right only matters if you are shooting with a fisheye lens. Otherwise a little (+/- 10mm) slack is okay. You can always touch things up in photoshop, which you generally have to do for panos anyway.
In 2006 I did a linear panorama of a 250m row of shops along a highway. Each shot was taken 5m apart and then approx. 80x were stitched together into a single image. 5m between shots: that is what I would call a fair bit of Nodal Point slack :?) 

The result?  The "Lawson GWH Heritage Shops" linear panorama at:

I use the Novoflex set up - see the URL:

Someone complained this is too expensive. Not really - see the 360 Precision mounts at:

... which weigh in at @ £540 UK Pounds (!)
FWIW I made my own VR mount years ago so I could use my Leica 16mm fisheye on a motorised M:

Since it is a "swinging mount", it can be pointed up for a vertical shot. This lets you shoot a full sphere with 8 shots: 6x horizontally, 1-up, 1-down.
