Qarl Fizz change his code posting and the missing parts are up. So, presumably Third Party Viewers have the code and are able to compile viewers with the feature.
Henri Beauchamp’s Cool VL is likely going to see a new version release today.

New patch ported to the Cool VL Viewer and working fine (a new release including it will likely be published tomorrow or the day after).
The issue with “jumping meshes” (see my comment for v0.2) is yet still not solved (but I implemented a work around for it in the Cool VL Viewer, that at least doesn’t trigger the “jumping mesh” issue with avatars not wearing deformed meshes).
I was unsure what Henri meant by ‘jumping mesh.’ I have seen mesh winking in and out of existence using Niran’s viewer… whatever, reading the referenced comment:
