+     <title>KISS Principle</title>
+     The KISS (Keep It Simple, Stupid) Principle is self-descriptive and recognizes two things:
+. People (including product and service users) generally want things that are simple,
+         meaning easy to learn and use.
+. A company that makes products or furnishes services may find simplicity an advantage
+         for the company as well, since it tends to shorten time and reduce cost.
+         (Where the company is trying to use the principle on behalf of users, however,
+         design time may take longer and cost more, but the net effect will be beneficial since
+         easy-to-learn-and-use products and services tend to be cheaper to produce and service in the long run.)
+     The New Hacker's Dictionary, edited by Eric Raymond, says the the KISS Principle
+     is sometimes cited on a development project to fend off "creeping featurism."

+   AtNewYork - Microsoft Unleashes Greenwich IM Beta
+   Thor Olavsrud
+   Adding steam to its efforts to build greater support for collaboration in the enterprise,
+   Microsoft unveiled the first widely available beta of 'Greenwich,' the code-name for its
+   new instant messaging and real-time collaboration server software. [snip]
+   The technology is designed to provide a central means that will manage all real-time
+   communications within an enterprise. Greenwich, slated for commercial release in mid-2003,
+   will integrate presence (knowledge of whether a person is online and available) into the
+   Windows Server 2003 platform to give enterprises access to voice, video and data collaboration.

+     Microsoft Greenwich
+     Breaking down barriers between people. Every communications mechanism -- e-mail, phone,
+     instant messaging, group collaboration tools -- forces individuals to adapt to its approach.
+     Microsoft's vision for next-generation communications uses Web services to enhance digital
+     meetings and group collaboration and provides information-agent technology to unify and
+     manage disparate communications mechanisms. Microsoft demonstrated its future direction
+     for real-time communications and collaboration (RTC) server software code-named "Greenwich."
+   from: http://www.internetnews.com/ent-news/article.php/1480181
+     [...]
+     In terms of security, Greenwich fully integrates with Microsoft's IT security management structure,
+     and will add protection to unencrypted text traveling across the Internet. Greenwich will also provide
+     standards support for technologies like SSL encryption, Digest and NTLM/Kerberos authentication.
+     [...]
+   from: http://e-businessadvisor.com/doc/12048
+     [...]
+     The Greenwich platform includes the following:
+     - Presence-based functionality that directs messages to available users
+     - Integration with the previously announced MSN Messenger Connect for Enterprises service
+       (see http://Advisor.com/doc/11494), which provides authentication and manageability for
+       business-to-consumer (B2C) instant messaging
+     - End-to-end communications based on industry security standards
+     - Administration based on industry-standard technologies and familiar tools
+     - Data collaboration, PC-to-PC voice and video, and other services
+     - IM conversation logging to help ensure regulatory compliance, customer service, and security
