solutnion #1 with no_reflection would be perfect, UNLESS :

A - object with no_reflection
B,C - standart objects with standart pov's relfection { }

now :
+ A will reflect sky-sphere and will look like with env_mapping
+ A will NOT reflect itself (if it is a complex shape)
+ B will relfect C (and vice-versa)
+ B and C will reflect A

but:
- A will reflect not only sky, but alsow B and C objects.

I know that the last effect is photo-realistic, but it disallow some 
artistics effects (and speed improvment)
