Humm,
about IDA I think that their protection is more a façade, just to safe theyrselves from blaming on piracy. Their tool is so powerful that should be sold only to accredited institutions..this is the common consideration of anti piracy coailitions. Moreover having the name of the buyer embedded into the program ensures an additional hand in protecting the program: which institution would see its name spread around?
After all I beieve that also they knows how technically weak is their protection.
If I was a technical manager at datarescue I would have done the same..
