Yes, the textures were chosen to demonstrate, or test, if the macros 
were working, while alluding to realistic possibilities.

Yes, I agree, these macros would provide one ingredient towards the 
realistic weathering of a model such as this.  But a very important one. 
  The thing that is notable here, I believe, is that while the macros 
could have been applied to the model as a whole, they are instead 
applied to each piece of the model individually so as to be more 
efficiently responsive to the finer details.  And, of course, they could 
also be applied to specific combinations of components for effect.

Thanks, Thomas.  As I am sure you can appreciate, there was a 
considerable amount of time spent with controlled testing to understand 
the effects of the different parameters.  Also I had to break down some 
of the coding in order to understand how they were working so as to 
understand how to apply them to a complex model such as this.  So right 
now this does not take advantage of some of the bells and whistles, such 
as adding random noise, which Eduard provides.  Though I did make use of 
the smoothing feature.

For the larger pieces of the model I used:
       #declare Proximity_SamplingDensity = 10;
       #declare Proximity_NumSamples = 10;

For the medium detail:
       #declare Proximity_SamplingDensity = 20;
       #declare Proximity_NumSamples = 10;

For the finest detail:
       #declare Proximity_SamplingDensity = 30;
       #declare Proximity_NumSamples = 10;

For smoothing:
	Proximity_SetPatternSmoothingValue( 15 )

Yes, I think that is crucial. In my building, up till now, I have applied 
the macros to the object as a single entity, but I was not entirely 
satisfied. I was just thinking the same thing when you mentioned it here.
