Can't see any point in elaborate copy protection schemes at all. They don't prevent those capable from hacking them from doing so, and they seriously upset legitimate customers. CC removed the dongle from Impression without damaging sales, and at a time when a larger market was more likely to throw up piracy. Sibelius still have to carry a support load for RISC OS product because of the installed base.
ANd, of course, drobe are confusing antipiracy measures with piracy. Piracy is not doing any threatening in this instance, Cerilica's system of licensing is.
