We are a TINY, tiny number of users, of mostly non-technical, computer-cracking illiterates

Why would anyone even BOTHER with cracking this, if the styles (the content) were so valueless to all but those with the arranger in the first place..? This isn't the trillion dollar movie industry. This is a few thousand users of a unique product. The trick is to make the bother of cracking it more expensive (in terms of hours of work) than the value of the downloadable product. Hardware keyed products are the toughest nut to crack.

My UAD-1 cards have been out for years, with all fully functional demos downloadable from the start, of quite expensive plug-ins. But they are keyed to the card itself. And as of yet, despite tens of thousands having been sold, no-one has cracked it yet. Some hacker kid in a bedroom in China (or Burbank!) is NOT going to bother trying to crack a protection system for a product he doesn't even have...

Audio computer software, especially the PC versions, are hacked almost as fast as they come out. But the UAD-1 card has remained untouched for many years now, despite it's VERY high value and quality, because of the hardware key.

THAT'S how it can be done...
