Niels,
If you're thinking about building or modifying a system to take
advantage of the latest methods, and your goal is to provide both
strength *and* convenience, take a look at the zero-knowledge
password protocols. These were specifically designed for
strong mutual authentication based on a short secret.
EKE, SRP and SPEKE come to mind.
These are available in a variety of forms, and can be used
where the host knows either a password, a hashed password, or
a public-key that corresponds to a password.
The page at www.IntegritySciences.com/links.html lists most
of the research in this area.
