While the technical barriers to sue of Linux in mobile devices have largely been overcome, device manufacturers still have concerns about the legal issues around use of GPL software in their products. The legal team at The Linux Foundation could provide a forum to discuss legal concerns among the members. Example topics include GPLv3 and the ability to change/update handsets, regulatory issues (i.e. FCC regs), DRM, and other IP liability concerns.
The Foundation could also help the developer community understand the legal and business issues that device manufacturers face in adopting Linux and defuse some tension through communication and education.
