+ * Echomail echoareas
+ *
+ * Security thoughts:
+ * + ZCs/RCs/NCs/HUBs carry all echos
+ * + echos for HUBs only (not NODES/POINTs, thus Hub/NC/RC/ZC)
+ * + echos for NCs only (NC/RC/ZC)
+ * + echos for RCs only (RC/ZC)
+ * YYRRRWWW
+ *
+ * Thus YY:
+ * + 0 - not exported
+ * + 1 - Sent to RCs (RW)
+ * + 2 - Sent to NCs as well (RW)
+ * + 3 - Sent to Hubs as well (RW)
+ *
+ * Thus RRR: (Read)
+ * + 0-7
+ * = 0 no read access
+ * = 1-7 minimum access required to perform
+ * Thus WWW: (Write)
+ * + 0-7
+ * = 0 no write access
+ * = 1-7 minimum access required to perform
+ *
+ * - If a node has 0, or an echoarea has 0, then no access to the function
+ * - So if node has 1, and echoarea has 2, no access to function
+ *
+ * @note change "public" to "bot posts"?
