There is a pattern that uses AJAX to create a PUSH-alike application. I don't know the real name of the paradigm, nor a good implementation, but this is basically how it works:

1. Client makes AJAX request to server.
2. Server doesn't close the connection.
3. When server wants to push. server says:
   a. Process push message X
   b. Initiate a new connection. (i.e. goto 1.)
   < Server closes connection >

So there is always a "hanging" connection, and as soon as the server wants to respond, the client immediately creates a new one that hangs again.
