+      <p>A D-Bus tube is an ordered reliable transport, for transporting D-Bus
+        traffic.</p>
+
+      <p>For each D-Bus tube, the connection manager listens on a D-Bus
+        server address, as detailed in the D-Bus specification. On this
+        address, it emulates a bus upon which each tube participant appears
+        as an endpoint.</p>
+
+      <p>The objects and interfaces which are expected to exist on the
+        emulated bus depend on the well-known name; typically, either the
+        participant who initiated the tube is expected to export the same
+        objects/interfaces that would be exported by a service of that name
+        on a bus, or all participants are expected to export those
+        objects/interfaces.</p>
+
+      <p>In a multi-user context (Handle_Type_Room) the tube behaves
+        like the D-Bus bus daemon, so participants can send each other
+        private messages, or can send broadcast messages which are
+        received by everyone in the tube (including themselves).
+        Each participant has a D-Bus unique name; connection managers
+        MUST prevent participants from sending messages with the wrong
+        sender unique name, and SHOULD attempt to avoid participants
+        receiving messages not intended for them.</p>
+
+      <p>In a 1-1 context (Handle_Type_Contact) the tube behaves like
+        a peer-to-peer D-Bus connection - arbitrary D-Bus messages with
+        any sender and/or destination can be sent by each participant,
+        and each participant receives all messages sent by the other
+        participant.</p>
