I was thinking about an Ajax request, constantly receiving data
(triggered by readystatechange) and updating the table. If the
connection is interrupted, the readyState would be 4 (completed), so
giving the possibility to catch a possible connection error.

I haven't tested 'cause I don't know how to make a PUSH page, but
anyway, wouldn't it work?
