Well, in my case, I absolutely do cache. In fact, I'll only update once a day. That update is triggered by a request to the service for that feed. There are two exceptions to that rule:

1. If a feed is indicated as having been updated by Userland's currentstories.xml file. In other words, I let Userland do the crawling and work out the feeds that need updating from their "meta" file.

2. An explicit request to renew a feed to my rewew page.

I would think that desktop clients should do something similar. There should be a single crawler, which generates a canonical changedSites.xml file on a server somewhere. Clients only update if a change is indicated there. If a mirror-ing arrangement could be worked out for that file, all the better.
