+/-2mm is quite a lot considering the size, but hey. it's coming, and only around the corner.

It is actually +-.2mm (about 0.008") in the article, which is why decimals should always be preceeded by a zero (ie 0.2) if there is no whole number component.

When I have a chance I want to test the accuracy of photomodeling software to see how it compares to laser scanning. I'm sure it won't be as good, but I would like to know reallistically what is achievable.

I've been taking classes on modeling for fabrication using Rhino, 3dsmax, and even a little Solidworks.  I model almost everything with 3d printing in mind, ie; "water-tight" manifolds.  It's not so much a concern in Rhino or Solidworks, but I usually STL check everything I model in 3dsmax for problems like holes, unwelded verts, or overlapping edges, which could cause real problems with 3D printers.
