Actually I was interested in a pad...not a seeded authentication
mechanism.  I realize there's a key distribution issue, but it's not
difficult to give out a CD with a few years worth of codes on it.

Seeded will suffice though, in lieu of rolling my own OTP.

I've been using SecurID at the companies I've worked at, so I didn't get
a chance to see what's on the open source network, but now that I'm
looking to implement this on my own systems, looks like a couple of the
tools people mentioned might work.
