It's not that easy: In case of ssh you configure pam for sshd on the
server machine. But you communicate the password to the client program
ssh. Since there is no generic communication mechanism between client and
server you cannot present arbitrary questions to the user. You are
constrained by the ssh-protocol between client and server. And that does
allow for one password.
