text mode password entry

[Allen Unueco]

I'm working on a command line client application.  It needs to ask the
user for a password and not echo the password back as they type.  I
can't find a way to do this without using the curses module.

This client needs to work on a few POSIX platforms and Win32.  I would
rather not have to install anything other then the standard Python
distribution.

Is this possible?
