I'd like to post time and current temperature on my digital sign. The only RSS feeds I've found so far only take me to a headline. Does anyone know of a free RSS service that will allow me to post this info? Or am I missing extra RSS path information that will allow me to directly target and request the data? Thanks.
You can just build a Flash or Javascript clock that runs on the DMP. As of 5.2.1 we enabled NTP service on the DMP. That means an app can query the time on the device.
Weather is a little harder. Check out http://www.weather.gov they have free text based weather data. You will need to download the data and parse it for the information you are looking for but thats not too hard with Javascript or Flash.
