David pointed out that if you want interactive content in a .cdf, you 
have to do so by means of Manipulate. But there are situations where 
Manipulate is much too restrictive and you want other Dynamic content, 
including DynamicModule.

Also, to promote the .cdf format and CDF Player and plug-in, surely a 
more attention-getting name than "CDF" or "Computable Document Format" 
is desirable? Yes, "CDF" has a nice analogy to "PDF", but so what. (And 
just wait for Adobe to catch on and sue over the use of "DF"!)
