I’m looking for a program that runs as daemon, downloads Atom and RSS feeds at least every minute, and provides a paginated Atom feed of all entries of all feeds through a simple HTTP server. It should also retain deleted entries. A useful extra would be to be able to label feeds, as in Google Reader, so that each label gets its own aggregate feed.
If you don’t know of such a program or know that it probably doesn’t exist, please let me know if you think there are any principle hurdles, because if not, I would queue it up as a project of my own.
The use cases are similar to that of services like Google Reader. I follow a larger number of RSS and Atom feeds and want to avoid having to regularly synchronize the list between multiple computers and my smartphone. On my smartphone, I also want to save traffic. In addition to those use cases, I need a high update rate, so I can react in a timely fashion, and to catch entries that are quickly deleted again, and I don’t want to have to leave one of my computers running non-stop either.
