Crowd Simulation Add-on

Is there any chance to get a more or less realistic Crowd Simulation Add-on? I have seen many "Workarounds-Videos", but they not really usable for realistic looking setups.

Crowd SIM have triggers, transitions, Foot planting, Behaviors such as Ragdoll, adding model diversity, Cloth and Material variation, etc.

Here is an example how it works note based in Houdini: youtube.com/watch

Hope Blender gets anything next time .... Thanks!
