Pushing SAX events out onto the Web?

Hi Folks,

I have a situation where I would like to stream SAX events across the
Web.  That is, I have a SAX parser running somewhere on the Web.  I want
it to push the events out onto the Web.  I want an event handler,
somewhere else on the Web, to catch those events:

 ------------                       -------------    -------------
 |           |                      |           |    |           |
 |   Event   |<---------------------| XMLReader |<---|    XML    |
 |  Handler  |          Web         |           |    |           | 
 |           |                      -------------    -------------
 -------------

Has anyone done this?  Has anyone created, perhaps, a Web-based
XMLFilterImpl that interacts with a Web-based XMLReader?  /Roger
