Thanks for sharing those links, that sounds like a very relevant project
and will hopefully benefit any potential candidates.
I am no programmer however, and my coding skills are (very) limited
beyond basic copy-pasting or scripting, so I can only hope they will help :)
Thanks for volunteering, glad to see there are developers interested in
working on these features, all help is appreciated, maybe you could
mentor/collaborate with someone else with more availability? I believe
in compensation for everyone's work, so if this ever gets done maybe
funding can be fairly distributed among participants? I leave these
matters to Ton, I have no knowledge of how this works.
About the more detailed proposal, I'll just leave it here before we
continue off-list so everyone can grab a basic idea, these would
eventually need to be shared properly somewhere like the Blender Wiki or
Anyway this was pretty much a relatively incoherent 'dump' of all the
requests I collected throughout my time with Blender. Many will likely
need clarification (let me know and I'll explain or even illustrate if
needed), and these will definitely need aggressive scrutinizing on both
technical and practical feasibility.

Let me know what you think!
