I'm using the mesh found in this link which is animated using shape keys. I'm wondering how I can do the same animation but using bones (armature) instead? So if anyone could please advise.

You can drive those shapekeys with bones, this is actually the preferred way of doing facial animations. This video explains in a detail how to setup the drivers and hook the bones to the shapekeys. In the first part he creates all the face-expression shapekeys and in this second one he drives them with bones.
I've been experimenting with facial armatures! I use envelope weights, weight paint, and bone constraints to mirror sides of the face, and I was trying to make a weird sort of pentagraph-like thing for shaping the outer mouth and cheeks

$\begingroup$ I know weight painting, this is not related to my problem. My problem is that I already have an animation done using shape keys but I want to use bone and weight painting instead, but to do the same animation made by the shape keys $\endgroup$– TakCommented Nov 11, 2014 at 6:17

$\begingroup$ So you have shape key animation all done; and you want to somehow transmogrify it into armature animation? huh... A brute-force approach would be to write a script that creates an armature with a little bone for each and every vertex; creates a pose library by applying all the transformations of each vertex to each and every bone; something like that? $\endgroup$– ball2000Commented Nov 11, 2014 at 6:24

$\begingroup$ I don't want to have a 4000 bone in case my mesh is 4000 vertex :) . What I'm thinking of is a bone for every shape key. What do you think? $\endgroup$– TakCommented Nov 11, 2014 at 6:40

$\begingroup$ That whole concept blows my mind. I don't understand $\endgroup$– ball2000Commented Nov 11, 2014 at 6:51

you could use the shape driver constraint add-on to control those shape keys. The bones could be constrained as the drivers. Here's the link to the website and video guides you through how to use the add-on: https://www.blendernation.com/2015/05/18/addon-shape-driver-constraint/
