True, but the downside is that many of the GUIDs stored under a given key will refer to offline peers, and the searcher can't tell which ones are stale without doing a GUID->IP:port lookup. So it gets quite expensive for searchers, especially if peers typically spend a lot of time offline. Cheers, Michael
