The previous comment regarding the intent of the seeker coloring the search strategy and thus the result also bears on the question about the minimal size of information. It should be obvious that the minimal size that can convey information is a single bit. For example, of the question is "is the power on? then meaningful information is conveyed with a simple "yes"--if more elaborate information is requested,l then the minimal size of acceptable information content in the reply must also grow. Thus, the minimal size of "meaningful" information is a function of the intent of the seeker.
