[SASAG] Experiences with CryptoCard?

[branen salmon]

Hi, all--

I'm wondering if anyone's had experience with CryptoCard's OTP tokens
and associated software [1].  On paper, they look pretty sweet--server
runs on CentOS, supports RADIUS, client modules for Mac and Linux--,
but I'd be most interested to hear if anyone can confirm or deny the
verite of their paper appearance.

Alternatively, if anyone has any positive recommendations for a nice,
open-source friendly OTP token system, I'd be similarly appreciative.

Thanks!
