+This is a plugin to automatically load notices in the browser no
+matter who creates them -- the kind of thing we see with
+search.twitter.com, rejaw.com, or FriendFeed's "real time" news.
+
+NOTE: this is an insecure version; don't roll it out on a production
+server.
+
+It requires a cometd server. I've only had the cometd-java server work
+correctly; something's wiggy with the Twisted-based server.
+
+After you have a cometd server installed, just add this code to your
+config.php:
+
+ require_once(INSTALLDIR.'/plugins/Comet/CometPlugin.php');
+ $cp = new CometPlugin('http://example.com:8080/cometd/');
+
+Change 'example.com:8080' to the name and port of the server you
+installed cometd on.
+
+TODO:
+
+* Needs to be tested with Ajax submission. Probably messes everything
+ up.
+* Add more timelines: personal inbox and tags would be great.
+* Add security. In particular, only let the PHP code publish notices
+ to the cometd server. Currently, it doesn't try to authenticate.
