FeederReader currently caches only the text that is in the feed itself. It does not do an *additional* request to get the Web Pages pointed to by the RSS feed. In many cases, this is enough to get the entire feed (or enough to be satisfying, anyway). For example (off the top of my head), infoworld, techinfo, wwdn, yahoo news (which is a few-sentence summary) are very decent feeds for those not wanting to cache the entire web pages.
FeederReader does (optionally) cache the embedded images within the feed, which works well with those feeds that include images.
I've been told by several of my users that FeederReader works with WM5.
Let me know if you have any other questions! I come around here every once in a while, but if you want an answer from me for sure, visit and post in the FeederReader Forums (
www.FeederReader.com sidebar "Forums").
