That's one possible (approximate) solution. But it needs at least triangle 
adjacency information (which opcode/tricollider doesn't have/calculate now). 
Well, adjacency isn't big deal and probably would be good in other colliders 
(eg. trimesh-box) as well.

This doesn't solve penetration depth though...
