That seems pretty reasonable.  I've gone a little into fannon by implying that the IDE has been sending interfaces throughout much of human history, many of which were persecuted and lynched before the IDE figured out how to interface with humans.  The coming of Haruhi, however, actually represents the first time the IDE is truly interested in what's going on with humanity, instead of simply indexing the activity of their civilization for completeness.<br/><br/>(Hence the activity of Data Entity rebels and Yuki's authorization to manipulate the data stream to an impressive degree.)
