A brief word of caution when using web content and RSS feeds in digital signage. BBC/CBC/ACCUWEATHER RSS and web content is subject to terms of use that are pretty murky when it comes to terms of use for digital signage. All of the sources however agree that they prohibit ANY "indirect commercialization' of content. One of my customers inquired with lawyer, and the answer was basically 'the low cost of licenced content is worth the peace of mind'. see the post HERE: http://www.tetraddigitalsignage.com/2009/11/news-update.html
2.3 YOU MAY NOT DIRECTLY OR INDIRECTLY CHARGE USERS SPECIFICALLY FOR ACCESSING BBC CONTENT OR OTHERWISE COMMERCIALISE SUCH CONTENT, NOR ATTEMPT TO RE-SELL THE BBC CONTENT IN ANY WAY.
2.4 Where possible you must create a functional link back to the BBC webpage summarised by the BBC Content . If you are displaying the BBC Feed where a functional link back to the BBC is not possible, you must display on-screen the URL from which the BBC Content can be obtained (scroll down to the accreditation section below.) You may not directly or indirectly change, edit, add to or produce summaries of the BBC Content or any content on the BBC website nor place any full-story BBC content in an HTML frame-set.
BBC's RSS T&C's as may apply to digital signage: http://www.bbc.co.uk/feedfactory/terms.shtml (Note similar exist for all other web conent)
