i've sort of worked it out in a tag instead. if you create spline, add the tag to it, then link to a mesh in the tag, the tag will modify the spline so it goes through all the vertices of the mesh. gives exactly the same result as the tracer with deforms and sweepnurbs.
one problem is that the spline disapears in the viewport sometimes.
