Who is needed to support this strategy (e.g., Wikimedia Foundation, chapters, individual volunteers, external partners), and what do they need to do?
Could organizations such as Engineers Without Borders (http://www.ewb-international.org/) be intrested in organizing translation groups? They probably are technologically oriented and understands the importance of knowledge. Their members are probably able to learn the basics of editing a Wikipedia easily and could help in organizing groups and provide technical support to translators. The translators could either be people that know an under-represented language or native speakers. It would make it easier for people that wants to contribute but lacks computer knowledge to help out, and might fit well together with the organizations educational projects.
