I was thinking that RSS 1.0 would fit this functionality very well.  In 
order to be a good netizen, my aggregator reads the my.userland 
currentStories.xml file and only grabs from sites that have changed.

http://static.userland.com/myUserLandMisc/currentStories.xml

My point is that currentStories.xml is a kind of first level aggregator 
that any site with multiple RSS feeds could use to indicate which feeds 
have new stories.  Any aggregator should go to such a file and use that to 
only grab what's new.

Where currentStories.xml uses the unique Userland ID (which I have to 
cross-reference to the RSS url):
<userLandChannelId>1946</userLandChannelId>

RSS 1.0 can use the inchannel
<inchannel rdf:resource="http:///www.pie-r-squared.com/rss.rdf"; />

Thoughts?
