+\r
+Thinking about this some more how about printing the name and address as\r
+a structured pair/map (at least for all cases except text/text0 output):\r
+something like (in JSON)\r
+[name: "John Doe" address: "john.doe@example.com"]\r
+\r
+It seems wrong to me to go to the effort of separating them in the C and\r
+then combining them in the output.\r
+\r
+This could also help with the questions about uniqueness. If the client\r
+can get the data ready parsed into name/address then it can deal with\r
+much of the uniqueness itself.\r
+\r
+My preference would be for the default to print one line for each\r
+distinct full_address, and then any filter-by options to refine from\r
+there.\r
+\r
+One other advantage of structuring the output is that it is extensible:\r
+for example, at some later stage, we could include a "count" in the map\r
+allowing the client can pick the most popular variant.\r
+\r
+Best wishes\r
