telnetd is not inherently bad. It is a tool that is lacking the session encryption and strong authentication features of SSH, but is still useful in some cases. Like any tool it can be used poorly, but that is not the fault of the tool.
Agreed.
For example, when traveling, I can log in securely from any random Internet cafe using OPIE or S/Key one-time passwords via telnet. SSH requires that you trust your local machine, and OPIE assumes that you don't.
Incorrect. OPIE assumes complete trust of your local machine, but not the network. You still have to generate the hashes using your password.
Not at all. You don't have to generate the hashes on your local machine. Most people using OPIE (or any one-time password scheme) have a hardware device (i.e. Palm Pilot) to calculate the hashes. As you say, it would be rather silly to calculate the hashes on the untrusted machine!
