Indeed. Many semiconductor manufacturers who are concerned about meeting 
FCC spurious emissions for non-intentional radiators will include a 
"spread spectrum" option to dither the clock.

One has to ask: "If I took some fresh cow manure and spread it over your 
dinner plate thinly and evenly so that you could not see it, would that 
be better than just having it as a pile on the plate?"
