+// Data offers are sent to clients to represent a data source that they

+// one data source (typically, one per data device).

+// A data offer and the data source it represents need not use the same
+// protocol: a client can ask to recevive data from a data offer using
+// one protocol, and Owl will ask the backing client to send the data for
+// the data source using another one.
