 I used this approach recently in putting together a demo in which four
laptops talked to each other, one after another.  It worked very well.
We actually wanted to open something on the receiving end that an
operator could see when the message came in.  But you can't push data to
a browser, especially one that may not be open (at least, not to IE,
which we used to be able to display the xml).

I wrote a simple little http server in python.  The sending end sent a
form to the server on the target computer.   The form contained the url
of the data page, which was an xml file.  On receipt of the posted form,
the server launched a browser instance pointed to the url.  I could have
done it with sockets, but using the browser to send the message took a
lot less time and engineering on my part.

This worked very well and was quite reliable.
