Most of Digithurst’s products, if specifications were massaged a little, slid off the industrial list of prohibited technologies. The exception was a device which, however you described it, was still IL1527. Our software key could, in theory, be used to encrypt communications; just about – sufficient, perhaps, for GeoCachers hiding the location of message logs from Muggles. Even so, alarm bells rang when we bulk-shipped Targa versions of the hairstyling software to Germany, each with a key.

IDR, however, felt that the CMD’s ability to display digital video in a window was unique.
