Mitch Kapor's Weblog: Microsoft Acquires Groove: "With the prospect of open source-based server capabilities of all kinds becoming more like the electrical power and distribution system, universally available on demand in whatever amount is needed, a whole class of objections to client-server architectures such as dependence on non-local, unreliable and inconvenient infrastructure diminishes. Groove's peer-to-peer architecture performs uniquely well in areas where the telecom infrastructure is weak, such as conflict-ridden areas of the Middle East and Asia where both military and humanitarian aid groups have deployed it successfully, but this alone is a niche application.
The challenge now is whether Ray and Groove, which represent forces of architectural innovation, can have a successful impact at Microsoft, which after all, is a large (58,000 person), middle-aged (30 year-old) company. It's hard to know whether the loss of nimbleness due to size and age is a greater challenge to Microsoft than is open source. "
