What follows is a loose proposal, if there is developer interest I will flesh it out more if needed.

Joint Plane Proposal

There is a problem with blender, as with most 3d software, where certain parts of a rigged mesh, ie. inside of elbows, back of knees, etc. have a tendency to have their opposite sides (above & below knee/elbow) clip into each other as default behaviour, the rigger then has to put a bit of effort into making each side have blend shapes so that this can be corrected.

I propose that a system similar to 3ds Max's physique be employed where joints between bones have a plane that ensures that verts above the plane stay above, and below stay below. The plane is aligned according to the average normals of the two connecting bones. there can be optional stand-off distances, falloff to that distance, perhaps even bulging if someone is brave enough to attempt that. These planes should be optional for each joint as they won't be relevant everywhere.

This could also help with the cloth/elbow problem, by allowing space between the character mesh and clothing mesh.
