I don't think that Wikinomics is globally distributed engineering design teams.

Based on my limited knowledge, your last post appears to represent the primary feature of Wikinomics. Wikinomics is a collection of people in a common domain who are working on their own projects.
Example are;
~ The thousands of people contributing to the Linux operating system while working on individual projects.
~ IBM employees, clients, business partners and even family members, from 160 countries participating in a wide-open brainstorming session called the InnovationJam.
~ Google employees are required to dedicate 20 percent of their time to personal projects.
Wikinomics appears to be a potential alternative to the improbable 'group effort on a common project'.
