Yes. One should use OPIE when he knows the connection is being eavesdropped
at his end and accepts the fact that carrying around a printed sheet of
paper with a few OTP-generated passwords is safer (or you could program your
PDA, HP49, whatever to generate OTP passwords for you, I suppose) than
typing a constant password for the eavesdropper to grab.

Otherwise OPIE is (usually) a security risk, as those sheets of paper are
NOT a good thing in the hands of just about 99% of the people out there.
There are better protocols out there to avoid plain passwords on the wire,
and ssh is one of them.

I have to use OPIE from work, however the "helpdesk" m***ns force us to have
PCanywhere and other such crap installed in our machines. I am not about to
let them have my passwords THAT easily if I happen to need to ssh out of
M$Winblows to a Real Machine(tm) to get some work done :-)
