RedMatrix
Dream it. Do it.
The RedMatrix (aka "red") is an open source webapp providing a complete decentralised publishing, sharing, and communications system. It provides communications (private messaging, chat and social networking), media management (photos, events, files, web pages) and enough other features to make your head spin.
What makes the RedMatrix unique is the built-in decentralised identity management. This ties all RedMatrix sites and channels together into a single super-network where the boundaries between different websites are blurred or seemingly non-existent. Other sites "magically" know you and can provide customised content and services based on who you are and what they allow you to see or do.
Warning: You may find it disconcerting and a bit "primitive" to go back to the old internet where every site asks you to login with a username and password; or where a single website failure can ruin the day for millions of people. In the matrix, you can go to another site and keep communicating with all your friends. Cool, huh?
For the average person, the biggest advantage of decentralised identity management is that you decide who you want to share stuff with, and if they aren't on your list, they're not going to see it. It's all under your control (we're big on privacy). Use the RedMatrix as a social network or a business website or for personal cloud storage or media publishing - or any number of other uses; limited only by your imagination.
