The HTML 5 draft includes an EventSource() object that connects to the server, and remains open to take a stream of events. My arsd.rtud module can help with the server side part of that. The Last-Event-Id http header is defined in the draft to help handle loss of connection. When the browser reconnects to you, it sets this header to the last event id it saw, so you can catch it up. This member has the contents of that header.
