RSS Feed Converter with UI

Main goal: To parse my yahoo pipes feeds and to offer them from my own server (to be more reliable than pipes is). Also to be able to manage these feeds over a simple UI Details: The tool i need is something like a simplified google feedburner clone. Using an UI one can add rss feeds from forign source (yahoo pipes). After the convertion it should be possible to call the feed from my own server, like [login to view URL] Of course my personalized feed should be updated when the original feed is updated. The convertor should have a caching function and save the (new) feed data in a mysql table for X days (for the case the original feeds is unavailable one day) The parsing script should be 'patient' since yahoo pipes is not really reliable. Sometimes it takes a while to load a their feeds. UI Functions: Add / Delete Feed Name feed Name feed url (e.g. feed1, feed2, myfeed2 etc.) Config the number of days for caching X List feeds Password protected login Very important: please take care of right encoding. I use german feeds containing special characters. Please ask if something is not clear. I will prefer Php, MySQL, XML experienced coders. Thank you.
