Actually, this is easy to configure now in /etc/sudoers, as of Ubuntu Lucid.
Edit that file and changing one line:
-Defaults env_reset +Defaults env_reset,pwfeedback
Save that file to disk and now try:
$ sudo -k /bin/true [sudo] password for kirkland: ***************
Note that as soon as I hit "enter" all of the asterisks are deleted, masking my password once again.
Now the question ... Should we change this default value for Lucid?
