These can be individuals or teams and they can be academics or industrialists, the point being that if we trigger a step change in the technology everyone should be able to benefit. +Due to our Open real time publishing of the Libre-SOC project, our work +can be forked by anyone at any time as a starting point or as a building +block for new projects, potentially taking the ideas and concepts in any +direction.
