Soft-body would have to be client-side only. There's no way I'd want that much data going across my net connection for every single frame. Neither I nor LL has that kind of collective bandwidth. I don't know if the server just reports a rigid-body collision or if it warns of impending collisions... though now that I think about it, it probably doesn't matter.
Vac-forming can be done in Maya I know. Unsure about anything else. I'm pretty confident Blender can do it.
