PixelMuncher - your problem here is that you're doing something like:
Attribute('joint1')
...which errors, as you said, because it determines 'joint1' is a Joint, not
an Attribute.
This is exactly as it should be. If you want this to work, you'd have to do
something like:
Attribute('joint1.translateX')
or
Joint('joint1') # or PyNode('joint1'), or Transform('joint1'), etc...
..depending on what it is you actually want.
