Just wondering… does anyone anywhere know of a webserver-based RSS aggregator that will run on an intranet?

Commercial, open-source, it doesn’t matter at the moment, I’m just interested to know what’s available.

It would help people share both internal and external feeds (subscription lists).

I’ve searched high and low but so far to no avail.

I wrote to the folk at Bloglines, but they said they had no plans on this front.
