I can certainly understand the need for access control & security, but with the use of a smart-card one-time password system, this is a moot point.

Huh? How are you going to stop a system from "illegally" (in the sense of the provider, contracts, or whatever) acting as -say- www, ftp, or whatever server with such a one-time password system? You'll need access control *based on IP addresses* to reach that goal!

No, no, no. The concept of access-filtering based on source address is easily spoofed, where the OTP password systems that I'm referring to are based on a concept of authentication-based access, which is much more reliable than a [possibly fake] source address. This is not a new concept. - paul
