1. use imag_map - generate texture.bmp (same as HF generation, but in 
normal color mode), process it in external program, use image_map in pov :)

2. in case of i.e. sphere :

sphere { 0 5.0001 material { /*glass*/ normal { blur 0.3 scale 0.1 } }
sphere { 0 5 /* ......... */ }

simmilar thing could be probably done for more complex objects.
In glass material I suggest :

texture {
  pigment { color rgbf 1 }
  normal { bozo }
}
interior { ior 2 }
