+ * classes that wish to do network i/o at a very
+ * high level of abstraction.
+ * = This class provides the ability to retrieve data from
+ * the network, of specified length and offset, and potentially
+ * use any protocol "under the hood" to do so. It currently
+ * uses HTTP. See Blob_Handler also.
