I think it's worth trying, because trying to read
an integer this way won't waste any CPU cycles -
Flash/Flex probably run select() or poll() internally
and just sleep - until anything arrives over the socket.
(Versus trying to pull anything every 30 seconds -
that will cost you CPU and also feel delayed).
And whenever an integer arrives, then you could
use that number to indicate how many records have
changed at your backend, so that you can use it to
provide feedback on the progress to the user
while fetching the updated data over HTTP.
