Dragon's Teeth Vineyards (DTV) is a South African wine producer that is considering whether to use genetically modified organisms (GMOs) in its wine-making process. GMOs promise to lower the costs of wine production significantly through increased yields and reduced processing times as well as significantly improve the quality of the final product via the use of GM yeasts in fermentation. However, the market acceptance of GMOs is unclear, due to perceived health risks and reactions from traditional "old world" producers who believe the beauty of wine lies in its craft, dependence on local soil and climate, and inherent variability.

Describes the development of ShareNet, an innovative knowledge management system used by a division of Siemens. ShareNet attempts to capture the knowledge and experience of Siemen's many dispersed sales and marketing units around the globe, making it available to all. ShareNet has to date been funded as a corporate initiative, free to all who use it. But as the telecommunications market has collapsed, the group that runs it is under increasing pressure to cut costs. As a result, it is considering charging users who subscribe to the tool in the belief that these users will willingly pay for it. This relies, however, on being able to demonstrate that the tool/system has a positive return on investment--a notoriously difficult task.
