Jim Bell wants to get rich running a key escrow business (:-)
Oh, but what a business opportunity! I assume a floppy can hold 1000 keys. Even if I undercut the going rate of $200 per year by a factor of 10, that's a potential income of $20,000 per floppy per year. A box of 20 floppies on the shelf, and I'm set for life!
Add in the cost of a bank vault and the ability to provide any key to an approved law enforcement agency (i.e., one that provides you with a legitimate search warrant for the key) with a 2 hour response time (24/7/365). Also, you will have to take in keys as they are provided. Hmm, the SecureCard (tm) I use to dial into my office system generates one key per minute. Assume there are a million out there. Assume keys are 64 bits (8 bytes) + 64 bits of card ID. 16 Mbytes/minute is, according to the back of my envelope, just under 1/4 mbyte/sec, so each of those floppy's will fill up pretty quickly, and you'll need a really, really, big safe to put them in. Of course, Jim probably knows this. Martin.
