Rounded edge shader

Hello,

I remember back in the days when I was working with Maya, it had this nice shader wich made edges look round at rendertime. That way giving nice specular reflections without modeling the mesh itself or adding bevels.
Is something like that possible in Blender internal and Cycles?

Actually I found a link for the same feature in Modo… for better understanding:

Please learn to use the support forums. Thread moved.

Agus was working on such a feature. Not sure what the status is at the moment.
