Does anyone know how it is possible to overlay a 2d-text 'label' over a
selected object so that it may float, sticked to its object's trajectory,
without changing itself in size and orientation (always horiz)?
That is, a kind of "floating label" for a rendered object.

Thanks.

I do not know, but :
  - using an orthographic camera
  - a text object with no_shadow & no_reflection, ambient set to 1, and 
diffuse to 0, scale & rotate & translate set to your will,

you could place a text anywhere on the picture.
First make it with a fixed camera, with the sky & up set to size*y,
direction k*z and right ratio*size*x.

Then try moving the camera with some translate & rotate.
Applying the same transformation to the text should make it follow in 
the picture.
