Hi - thanks for testing and for the comments 👍

Let’s move some of the concrete ideas to [github issues for this repo](https://github.com/pieper/SlicerProcesses/issues).

Regarding standard pickling for vtk/Slicer objects yes, I looked into to that but it’s not in my critical path. There is something in tvtk for pickling. If this processes approach turns out to fill a general need there are lots of ways to improve it. I’ll add some notes about potential next steps in the readme file.
