Custom RSS Feed Component Joomla 1.5

We are looking for a extended RSS Feed Component for Joomla 1.5 All the standard components dont meet our requirements. The aim of the component is, that it should be possible that another website can integrate our news only by reading our rss feeds. Therefore we have got a certain specification, how the feed should look like. ## Deliverables On our website we have different types of news. We sorted them into different categories. - news about the center (our company) - news about our start-ups and alumni (other companies we have assisted in the past) rss specification for news from the center: <?xml version="1.0" encoding="utf-8"?> <rss version="2.0" xmlns:atom="[login to view URL]"> <channel> <title>text?text?text</title> <description>text?text?text</description> <link>link?link?link</link> <pubDate>date...date...date</ pubDate> <category><![CDATA[ID of our center]]></category> <item> <title>text?text?text</title> <link>link?link?link</link> <description>text?text?text</description> <pubDate>date...date...date</pubDate> <guid isPermaLink="?">link?link?link</guid> </item> </channel> </rss> ID of our center --> constant string rss specification for news from a startup or alumni: <?xml version="1.0" encoding="utf-8"?> <rss version="2.0" xmlns:atom="[login to view URL]"> <channel> <title>text?text?text</title> <description>text?text?text</description> <link>link?link?link</link> <pubDate>date...date...date</ pubDate> <category><![CDATA[ID of our center]]></category> <category><![CDATA[shortname of start-up or alumni]]></category> <item> <title>text?text?text</title> <link>link?link?link</link> <description>text?text?text</description> <pubDate>date...date...date</pubDate> <guid isPermaLink="?">link?link?link</guid> </item> </channel> </rss> shortname of start-up or alumni --> also constant, but it should be possible to add shortnames, if there is a new start-up. maybe possible by adding new categories in joolma? Feed-View: Like in other rss-components the feed should be listed in a certain order. In this view all news-entries should be shown. In addition it should be possible to open each news-entry (content) by a specific link (similar to wordpress) in the feed-view (not only linking to the original joomla content!) example-link: [login to view URL]
