 At a high-level this system consists of three layers: the grid, the
 filesystem, and the application.
 
-The lowest layer is the "grid", a mapping from capabilities to data.
-The capabilities are relatively short ascii strings, each used as a
-reference to an arbitrary-length sequence of data bytes, and are like a
-URI for that data. This data is encrypted and distributed across a
-number of nodes, such that it will survive the loss of most of the
