Heya Nick Seems that we are on parallell paths. Also looking into this. The solution I'm working at the moment is to use Gear > Animation > Edit Mirroring Template. http://prntscr.com/2vrpoc
After that you just need to go to Gear > Animation > Mirror Pose or Mirror Animation and it will apply the selected objects transforms to the one in the rules. Pos X and Rot Y will need to be inverted. Only thing I'm still looking at is to have the template being generated automatically. Someone told me it does, but when I select two controls with L and R in the mix, the rules just point to _self and not the pair. When you look at this it looks like very nice :) https://vimeo.com/71429800 but apparently not shared.
