We have been working on a new clustered file system. Using the resources available to us we have built a file-system that redundantly spans multiple servers. This allows us to add nodes into the cluster on the fly to meet the constant demands of extra storage. It also allows for us to have hardware failure at a drive or server level without any loss of data. We have successfully implemented this and are using it internally for backups of our VPS Servers. We are ready to start offering this as a new product.
