Mettā is an OS for mobile, multimedia, and social applications. Mettā's purpose is to be easily deployable over a range of mobile and home devices, without tedious setup procedures, while allowing people to communicate easily in a very ambient way and express themselves freely by creating, modifying, and publishing text, audio, and video information in a simple way. Mettā's flexibility comes from transparent resource manipulation and transparently distributing computing tasks between nodes on the network, while maintaining data integrity and privacy.
