Has the advantages over RAID that storage is encrypted, any mix of capacities is fine, redundancy is freely selectable per file, and recovery does not require entire disks. * *friendnet*: You and your friends share a virtual filesystem. It remains accessible even when some of your friends' computers are unreachable. Your friends can't see your files by default, but you can share individual files and directories with individual friends or with all friends. * *proprietary grid -- 1x upload*: Pay $5/month and you can store your stuff on their grid. Or: run your own grid by buying a few servers, so that you can backup your own stuff on it. The data is uploaded to the servers over a streaming protocol such as HTTP (using the Web API). * *hivecache*: Install a tahoe node on each of the workstations in your office, turning their unused disk space into a giant storage pool.
