"I would be happy to share for example my Janet morph, but ...

Smith Micro will not allow me to share the whole Janet-for-Roxie .pmd

and Poser does not provide a tool to produce a .pmd and inject pose with selected morph channels."

I am a little curious about this statement because .pmd files only contain delta data, unless you created the pmd from a non-blank character and included poser distributed morphs.  Create a FBM, load a blank character, load the fbm and save with binary morphs on should give you a clean .pmd with no poser morphs.

For the On-topic part of the post:

I use dawn whenever possible, but use V4 for Items/morphs that I can not duplicate with Dawn.
