Madsen,
Have you seen this? http://www.geometrysystems.net/default.htm
I have not tried it myself yet, but it's on my list to evaluate. There are numerous products out there that handle poly to nurbs conversion, but as far as I know, there is no app that will let you model in nurbs as "easily" as in polys.
T-Splines was definitely going in the right direction, although where its going know as part of Autodesk is unclear. The hope of T-Splines for me as well as others was that I could take a poly model and convert it to nurbs, and still easily modify it. However, the purpose of T-Splines, I keep reminding myself, is actually to creat a control mesh or low resolution proxy, to easily modify a nurbs object. It was never promised as a poly to nurbs converter simply because it is not designed to handle the sheer number of polys that are present in a detailed model or scan.
Geometry Systems is interesting because they seem to indicate the poly model, from a scan lets say, is tied to the nurbs model, so if you modify the polys, you also modify the nurbs. While superficially similar to T-Splines, they actually handle the full scan data. In theory this sounds great, but in actual use of the software, I don't know. I have to try it for myself.
