Looking for a "tweening" ruby script

[pns000]

Curious if anyone knows about a ruby script or is willing to play around with the idea of creating one that does the following:

• prompts you to select a face (or group of faces, this could be selection by hand or an already grouped set)
• prompts you to select a line (or group of lines, this also could be selection by hand or an already grouped set)
  -the scripts then takes the faces (or group of faces) and puts instances of them at every vertex in the line selected in the step before (like a preview mode showing each set of faces at all the vertices in shadow, then perhaps a toggle to also preview the tweening based on the orientations of thefaces at each vertex)
• at this point you can change by hand the orientation, position, rotation of the faces (as a group) at each vertex however you like. I also imagine a toggle mode to this where you can mimic the movements to the faces at verticies farther along the line away from the original or just modify each set of faces at each vertex individually.
• once you are happy with everything, you set the script in motion and it basically stitches or "tweens" faces between every group of faces at every vertex along the line.

With a script like this, you can overcome the follow me tool's shortcomings of twisting objects as they move along a path(line) that changes in more than one plane. Anyone?
