Just noticed on Scott W's site, hidden in one of the comments is a link to a project called Syndicache, this is a stunningly interesting idea. What this seems to provide is a method of using NNTP as a central aggregator for RSS feeds, have a look here for an example. It has always struck me how similar news aggregators like FeedDemon are to news readers, this project seems like a logical step, utilising a widely accepted infrastructure for the consumption and propogation of feeds.
Now we just need a reader capable of displaying the results nicely...which Steve Tibbett seems to be working on as well...could be worth watching!
