Ah yes, and if Zope has the ability to pull in and parse RDF from other sites, you would have a standards based mechanism for sharing/syndicating content among Zope sites (Clobber Vignettes iSyndicate).
I would love to be able to 'subscribe' my sites to subsections of www.dmoz.org (for example), add my own value-added content, and then allow other sites to 'subscribe' to my value-added version.
Note that this general mechanism could be used for almost any type of content, including Slashdot/Squishdot style news articles and comments, directories such as www.dmoz.org, event calendars, image galleries, etc.
