Constant Current Source: How about a Current Limiting Diode?

Carl B.Constant Current Source: How about a Current Limiting Diode?
Hey guys,  
 
I've a "specialty" diodes catalog and was thumbing through it. Zeners, schottkys, etc.  
 
What caught my eye was the two-terminaled "Current Limiting Diodes." Very independent of voltage (until some drop-out limitation of course), various models with various currents (micro to tens of milliamps).  
 
Why aren't these used more often, instead of using a tube or fet as the current limiting "plate-resistor-high-impedance-replacement?"  
 
Or are they used often? I'm somewhat "green" to the high-end/hifi performance tweeking measures.  
 
(And just what *does* "SRPP" stand for anyway?)
