+      delay-tolerant networks for fire-and-forget secure reliable files,
+      file requests, Internet mail and commands transmission. All
+      packets are integrity checked, end-to-end encrypted, explicitly
+      authenticated by known participants public keys. Onion encryption
+      is applied to relayed packets. Each node acts both as a client and
+      server, can use push and poll behaviour model.
