Animating multiple characters using the same link? (Crowd animation)

I think these studios use addons to accomplish this. I’ve never used this, but maybe the Crowd Simulator addon makes this easier.

@LordOdin says that his studio uses in house tools to manage scenes with lots of instances:

I don’t know if they share that with the public, but you could ask him if their tool is available on github or something like that.

I have the feeling that this was a technical limitation in the older versions of blender. There might not be any easy solutions you can use for this in 2.79.
