Our next T-Splines Rhino build will be available next week (the current items in the queue weren't conveniently chopped up into one-week blocks.)
However, I did produce a video showcasing T-Spline lofting. The video, along with a script, is hosted on our Rhino Plugin forum.
The basic gist is that you can loft a surface with T-Splines with varying levels of detail.
