Probably not ideal, and definitely not as cheap, but at least you'll deliver working prototypes and in the meantime, it will give you a chance to figure out the OTP problem. I know this doesn't help much, but I'll keep thinking about it and if I come up with anything, I'll let you know ASAP. Regards, Jim >>
