title: Node js - Creating persistent private chat rooms
body: <p>I've been reading so much a bout node js lately, and the chat capabilities seem very nice.  However, the only chat examples I've seen basically broadcast a chat server to a fixed URL (like a meeting room).  Is it possible to use node js in part to create a chat client more like gchat? - where a chat window is popped up on the current page and then persists through multiple pages.  Has anyone seen an example of this yet?</p>
  
  <p>If not, suggestions for other technologies to use for this purpose (I know that's been answered in other questions)?</p>
  
  <p>Thanks.</p>
