I always wondered if it would be possible to launch a small satelite from a balloon.

  With a rocket too, possibly. http://en.wikipedia.org/wiki/Rockoon http://en.wikipedia.org/wiki/Rockoon

  The real energy cost with obtaining orbit is the high transverse velocity, not the height. You need to reach velocity whereby the net motion ("falling") vector is towards the horizon. Gravity is only marginally less at higher altitudes even up to 100K feet.
