[Paraview] Stream tracer can't penetrate VTK_CONVEX_POINT_SET cells?

Marching cubes would definitely not work (it works with uniform rectilinear
grids only, i.e. vtkImageData) but you can still use the contour filter. It
_should_ work. I never used it so I can't guarantee it.

Any idea when the stream line feature would be in working order?

Also, has any progress been made in the realm of block structured adaptive

Yes. Read the article on composite datasets in the Nov '06 Kitware
newsletter: http://kitware.com/products/newsletter.html
We are actively working on further improvements.
