Hi Chris,
Yes, I had seen S5 before and thought it a pretty nifty setup. But does
it allow the operator to control page-advance in real time? The idea is
that if you're having a meeting with one or more remote viewers, you
could discuss by phone while showing them one slide at a time, at your
discretion.
The nice thing about AJAX is the first "A", "Asynchronous".
How much trouble would we cause if a page's onload event called an AJAX
function called "getNextSlide()". Upon receiving the request, the
server could sleep until a new slide is loaded (or sleep for 2 seconds
and check, sleep for 2 seconds and check, etc.).
Once a new slide is loaded the server finally sends a slide back to the
browser. The AJAX on the browser activates the slide and then calls
getNextSlide() again, re-starting the loop.
As always, the balance is between responsiveness and drag. You can get
away with this for a few users, but having a lot of open connections
checking something over and over will die fast at high volume.
