Is there a way to have my emission shader only affect the particle system?

Question

I have a scene that has a particle system and other objects. The particles are an object with a pure glossy shader. I have a plane that I have setup as an emission shader to reflect off the particles. However it is washing the other object in the scene. Is there a way to have my emission shader only affect the particle system?

Thanks

What you want is light groups. Well, the light groups feature hasn't been implemented in Cycles yet. If you wanna separate lighting on different objects, including particles, using Cycles, you might use render layers. Here's a solution for a practically the same question as yours.
