You might be interested in the latest nightly archive
(http://geuz.org/gmsh/src/): it contains a generalized
Plugin(Triangulate) that can transform vector valued
points into vector valued triangles. If your points lie
in a plane, it should return exactly what you need to
use the streamlines plugin.

Best,

Christophe
