+ * TODO:
+ * - soft stateing (keep-alive (CHANGE?) / timeout / disconnect) -- not a message issue
+ * - error reporting (CREATE/CHANGE/ADD/DEL?) -- new message!
+ * - partial disconnect reporting -- same as error reporting?
+ * - add vs create? change vs. keep-alive? same msg or different ones? -- thinking...
+ * - speed requirement specification (change?) in mesh API -- API call
