Please heed the lessons already learned in the software industry... Copy protection doesn't work. It works about as well as locks on doors as it'll keep the honest people honest, and offer a small obstacle to the dishonest. As others have stated, anything *you* can do with a PC floppy drive, *I* can do. (And given this thread, I can probablly do a few things you currently cannot.) Ultimately, any copy protection comes down to the software on the floppy. If the machine can read it to execute it, the hacker can read it to remove the checks. No ammount of hand-waving will change that. (That, btw, is why the DMCA, et. al., exist.) --Ricky - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
