Performance can be a problem. /rss.rdf on jspwiki.org is hit quite often (RSS readers go there every 10 minutes or so), and if, for every single hit, we need to serve a non-cacheable response (since the feed would be different for everyone, based on their permissions), it would be quite a heavy hit. /Janne
