Hi, I have an update.
After two weeks of beta, there is noticable progress.

The support for deformers has been improved.
We had some excellent results. The thing seemed to work on any kind of deformation, in any pose.

There remains a struggle with things that look like Poser Bugs (or I am too stupid).

For example, some body parts of some figures, show distortions if the morph target says the vertexes should NOT move at all. If the script says they should move like 0.00000001 instead of 0.0 , then it works. Maybe there is some memory leak or overflow, I do not know. Asked SmithMicro for assistance. 

What I find interesting is: If I pick such a body part on the affect figures, fresh from library, and go to the menu to say "SpawnMorphTarget". When I dial the new morph to 100 (not working with the brush on it, just dial it), there is a massive distortion, but it looks different than the ones my script makes. One the other body parts, this does not happen. Does anybody know why SpawnMorph Target from the menu could show such a behaviour? I would assume It makes a clear, empty morph. Am I using it wrong?

On poser 2010, Freak 4's finger locks after the script ran. Again something I cannot explain yet.

Otherwise, everything worked :).
