Especially if it can cover an extra controller for each knee as seen in Auto-Rig Pro or whatever system it is they use at the BF. Trying to correct for knee-pop is so much easier with something like that.
Another +1 to the request for rigging courses. Totally agree with davejkane would love to have a basic understanding of rigging so I could create a rig an animate any object for example a protein or a virus.
