[Bf-cycles] Feature: Per-Object or Per-Material Samples?

[Zauber Paracelsus]

Okay, I'm not familiar with blender's internals, so I don't know if this 
idea is viable or not.  But one thing I've found with Branched PT is 
that although it is very good at targeting noise sources, sometimes it 
isn't enough, or it does too much where it isn't needed.

One thing I've found myself desiring is the ability to boost the sample 
count for either (A) specific objects or (B) specific shaders.

For example:
1) I may have many glossy objects, but only one of them is producing a 
lot of noise. Simply ramping up the glossy samples will make all glossy 
objects take up more render time.  However, if you could set a sample 
count for that particular object, then
2) Particularly small or thin objects (such as hair) may need a great 
number of samples in order to get rid of noise.  Being able to increase 
the sample count for the hair itself either via the emitter or the hair 
shader would be very useful in this case.


So, any thoughts or suggestions?  Again, I don't know the internals of 
blender or cycles, so I don't know if this is a viable option.
