What technologies should be used?
Initially due to budget constraints, space, health and safety issues, the initial community should focus purely on computer and IT technologies. These provide the most utility for the lowest costs.
As for software a primarily open source approach fits in line with an organisation trying to help the world and future generations without extending the price tag.
As the community expands, gains members and space more labs and additional technologies can be integrated.
For the sake of expansion and diversity of members these labs should initially be multi-purpose.
