How to design a static prefab class.

Heys,

I wanted to created a static prefab class, as prefab reference for all of my scripts, like:

 static class Prefab
 {
         public static Transform prefab1;
         public static Transform prefab2;
         ...
         public static Transform getPrefab(string name)
         {
                 ...
                 return prefab;
         }
 }

but there is no way to link a Transform/Rigidbody to a static class member, so how to do it?

(Oh and please do not come with Singeltons, thats no solution)

Cheers
