Unsure when this was added but Microsoft have added 2 services to their Sandbox website for public testing.

The NetScan system data mines Usenet newsgroups to provide tools to discover new newsgroups, select high quality content from them, evaluate the likely reliability of the information, and, possibly, motivate participants to make valuable contributions by providing a service that can be thought of as a reputation system for communities. Try searching for your favorite hobby, software, or TV show to see how it works.

The TerraServer-USA Web site is one of the world's largest online databases, providing free public access to a vast data store of maps and aerial photographs of the United States. TerraServer is designed to work with commonly available computer systems and Web browsers over slow speed communications links. The TerraServer name is a play on words, with 'Terra' referring to the 'earth' or 'land' and also to the terabytes of images stored on the site. Exploring our planet by studying maps and images is a fascinating experience! Not surprisingly, the first place many people visit is their own neighborhood. You also might want to take a look at famous places such as our National Parks or your favorite sports parks. TerraServer is also a valuable resource for researchers who was to study geography, environmental issues or archeological mysteries...there are almost limitless possibilities.

You can easily navigate the enormous amount of information in TerraServer by selecting a location on a map or entering a place name. And now, a new Web service--called TerraServer.NET--enables Web developers to easily integrate TerraServer data into their own applications. TerraServer is operated by the Microsoft Corporation as a research project for developing advanced database technology, and was born at the Microsoft Bay Area Research Center. TerraServer's foundation is Microsoft SQL Server 2000, the complete relational database management and analysis system for building scalable e-commerce, line-of-business, and data warehousing solutions. Equipment and additional software is provided by the Hewlett-Packard Corporation and other partners. See Technology Behind the Site for more information. Maps and images are supplied through our partnership with the U.S. Geological Survey.
