+ * @section Purpose Purpose/Goal
+ *
+ * Create an alternative to ZigBee radios for Arduino communication.
+ *
+ * Xbees are excellent little radios, backed up by a mature and robust standard 
+ * protocol stack.  They are also expensive.
+ *
+ * For many Arduino uses, they seem like overkill.  So I am working to build
+ * an alternative using nRF24L01 radios.  Modules are available for less than 
+ * $6 from many sources.  With the RF24Network layer, I hope to cover many
+ * common communication scenarios.

  * The layer provides:
  * @li Host Addressing.  Each node has a logical address on the local network.
  * @li Message Forwarding.  Messages can be sent from one node to any other, and
  * this layer will get them there no matter how many hops it takes.
- * @li Ad-hoc Joining.  A node can join a network without any changes to the
- * existing node.
