Yes but it is a very clever kludge that allows HTML/AJAX to do something it
wasn't designed for.

You are making the wrong comparisons.  Servers CANNOT send data to clients
unless the client initiates a request for data.  A client keeping a SINGLE
connection open by sending a char every few seconds is MUCH less bandwidth
intensive then polling.

Remember that polling requires setting up a connection and tearing it down
over and over.  Certainly you agree sending one char is better than THAT?
