The answer is:

'A SDK produces an anim curve, thats all its really doing. So if open up the hypergraph and find the curve, u can just dup it and connect it to the mirror joint and the mirror driver. Depending on ur joint orientation u might need to flip some of the animation in the graph editor, or stuff in a reverseNode.

Its something thats best of scripted tho.'

Hope it works. You can thank Andimation at www.Jonhandhisdog.com in the general questions forum if it works
