You are correct.  The prompt is for your own password.  There is no
prompt for the "ventrilo" user password. sudo creates a timestamp file
and will only reprompt you for a password after 5 minutes of inactivity.

If you use sudo in a script which is run by an ordinary user, you will
still get the password prompt.  As explained earlier, if you want to
allow users to run a command using sudo, but suppress the password
prompt, use the NOPASSWD flag in the /etc/sudoers file for the command.
