As PS already looses all infromation about the objects, maybe you
should start one step earlier.

I guess you need some kind of parser for the InputForm of your graphics
object, which might be quite simple for a single Point
In[11]:=
p = Graphics[Point[{1, 1}]] // InputForm

Out[11]//InputForm=
Graphics[Point[{1, 1}]]

I guess, this is what happens in the LiveGraphics3D Applet by
