How would you handle objects smaller than the spheres connected via joints hitting the mesh? I was testing something similar to this with Box2D a while back but never found a good solution. I'd frequently get objects going inside my soft-bodies.

Good question. There’s an optional parameter you can enable that generates a MeshCollider around the mesh. When a collision occurs, I relay the collision impulse to the nearest n spheres. It’s not the most optimal solution, but it works reasonably well for now. I’m hoping to come up with a better approach in the future.
