So I should be able to make one set of arm and leg and just duplicate them with the bones and smart bone actions intact right?
Is this possible? I'm concerned that the actions will conflict in some way.
If you know of a tutorial that shows how to set up a side view walk cycle, please tell me about it.

It's an odd sort of animal leg that will look human in the raised position and more animal on the down, so I'll need to do a bit of point adjustment and I'd rather not have to do it twice.
