@inevitable, I actually found a great example for you. This is a playground that has multiple meshes skinned to the same skeleton as well as shows how to attach a mesh to a bone. As you can see there are several meshes all pointing at the same skeleton which all animate together:
And the attachment of the sphere to the hand bone is accomplished with the code:
sphere.attachToBone(skelenton.bones[34], dude);
Hope this helps point you in the right direction, but you can find more in the bones and skeleton documentation page.
