Sorry if this dupes, looks like my first message is in limbo. We agree: The Pipe Implementation will have a read(<ConfigObject> , CallBack) method Config Object will include pagining information The biggest difference between our current proposals that I can see is where and how are the calculations for Paging done and provided to the developer. In iOS and JS (from the examples) the User provides and updated configObject with an "action" param to the read method. In Android the response dataSet includes convenience methods which call the pipe using the appropriate parameters. Is that there actually is keeping us from having this thing nailed down?
