Thanks Stefan!

I'm afraid this is a bit too much hassle for me. I've always avoided going the Homebrew route. Back in the good ol' Amiga days I loved to dive deep into such things. Nowadays I've developed enough patience to wait for an easily usable implementation, without hacks and workarounds. :)

But I'm eager to use it as soon as there's a GUI or integration, maybe into Blender. I've started a topic at the Blender Artists forum about it:

If you respond to the thread, it will be bumped up to the top of the thread list again. ;)
