Andrew,
I was reading this article
https://www.haiku-os.org/blog/animortis/2021-04-27_my_first_week_with_haiku/
Thanks for passing this along.  I read the article and it is quite interesting; it looks like they have done a lot of work and I am sure that they will get some developers who would like to work on it. 

I do not think Cin can be easily ported to it, at least as gui app (no X server there, yet?), but this is interesting effort, imo more interesting than using Linux gui apps on still closed-source (and worse) Windows... 
Sounds like "no".  I wonder if they have ffmpeg going yet.

Also, can anyone try accessing cinelerra-gg website via tor with javascript disabled? 
Hmmm?
