dupli groups - duplicate mesh along text?

Is it possible to duplicate a mesh over text? e.g. in courier new I write Hello, and i want to cover that space in spheres (edit:arbitrary 3D object) without placing each object individually. I've seen examples of using dupliframes along curves, but is it possible to do it along text?Edit: I also found out I can convert the text to a curve, but it seems the duplication only follows the outline of the text. Can I do a "fill" with my object?...Read more
