With our site we would like to provide a registration process to new users in such way that a new account and an according contact is created each time a new user registers. As a result after the successful registration there should be a new contact that belongs to a new account and this contact is linked to a newly created user.

Is that possible and how can we achieve that?

The documentation we found http://wiki.developerforce.com/index.php/Authenticating_Users_on_Force.com_Sites just provides an example where all newly created users and contacts are tied to one account.
