ACS authorization plugins + configuration

Question

Hi,
there have been rumors that there is a plugin providing an API that allows you to authenticate user with a given name/password
combination. I.e. the users do not necessarily need an Adobe account.
The rumor also says that this is somewhat related to Barnes & Noble's nook device...
All I found so far is
http://www.adobe.com/devnet/digitalpublishing/articles/barnes_noble_faq.html
Can someone tell me where to find more detailed information. In particular how to download, install and configure that plugin
(if it exists). The interface to be implemented is called "PassHashInfo", but cannot be found in anywhere in the ACS' WAR or JAR
files.

5.1   PasshashInfo Interface
The PasshashInfo Interface provides the mechanism for providing the encryption key for the document
encryption key during fulfillment when using Passhash based protection. The interface itself is a single  function:
byte[] getPasshash(String transactionID, byte[] userID, byte[] distributorID) throws PasshashException;
The transactionID and distributorID are specified in the fulfillmentToken. The userID comes from the
fulfillmentRequest, which also contains the fulfillment token. Given these three pieces of information, it is  the responsibility of the ACS4 operator to determine the appropriate username and password to be used,
and to generate the encryption key. It is the joint responsibility of the Distributor and the AC54 operator
to communicate the username and password to be used to access the content, prior to initiating the
fulfillment.
It is expected that the AC54 operator will work with the distributor to retrieve the passhash to be used
from the distributor. The exact mechanism to be used for this is outside the scope of ACS4.

9    Password-Based Document Protection
New in ACS 4.1 is the ability to use password-based encryption for protecting the document encryption
key, instead of the current Public key-based encryption tied to a specific Adobe DRM user. Since the
content is not tied to a particular Adobe DRM user, there is no activation required and therefore no limits
on the number of devices the content can be used on. Because of the lack of activation requirements,
neither returning contents (loans), nor consumable permissions are supported when using password-
based document protections.
Ths password-based encryption is different from the password security offered in the Acrobat file format,
in that it requires a username and password, it is compatible with ACS, and the resulting files cannot be
viewed with Adobe Acrobat or Adobe Reader.
Password-based document protection is also referred to as ''Passhash''. To issue content using Passhash
protection, you must create a DistributionRight for that content with usePasshash set to true, and supply
the encryption hey to be used to the fulfillment service using the passhashlnfo interface. To set up the
DistributionRights correctly, you can either use the adminConsole or directly call the
ManageDistributionRights adm in AP l to set usePasshash to true for the DistributionRight. To configure
the fulfillment service to look for your custom class that implements the passhashlnfo interface, in your
fulfillment configuration file, you will need to set the value of the
com.adobe.adept.fulfillment.passhashInterface
setting to be the name of your class. You will also need to
place your .jar file into a location that is in the library path for Tomcat. The Tomcat Libraries directory is
usually the most convenient for this. For more information on the passhashlnfo interface, refer to the
Technical Reference .
