I can assure u, ur are not the only one asking that question

Order-Independen-Transparency/-Transluceny is a more or less an unresolved issue in computer graphics and is a very hot topic in research.

A common technique is called "depth-peeling" wich tries to render the scene in a number of z-slices (e.g. take this paper by Nvidia for a refined implementation in GL). Also techniques using the accumilation buffer or "Screen-Door-Transparency"-techniques are often used.

If u are searching for a very simple mehtod with completely ignores odering of the polygons maybe simple "additive blending" may work for the usecase u showed above.
