Hi Tim,
I played around such a thing a short time a go with servlets, jsp and
Allaire JRun, but i'm sure it's possible to make the following with cfml
too - even if i have not time to code it now ;)
from conference page you can login as speaker ( password needed ) or
listening user ( eventually with password ).
if you log in as speaker you just go through the slides with a <input
type="submit"> button: you can see the jpg file and autmatically, as you
flip page, you send something like an update signal.
i've done that with a static class-scope field with synchronized access in
Java, if you know that, but you cerainly can do that in CF, too - personally
i use cf only for presentation porpuses and i leave logic matters to
servlets.
if you log in as listener you can see the active slide a that moment while
"behind" a javascript code periodically ( 10 seconds in my case ) checks for
the update signal.
i've done the javascript auto-check with settimeout and i recalled the page
itself, where i check the golbal feld for a new image, eventually update it,
and then prints out itself.
Just pay attention not redraw the page every 10 seconds or it will be awful,
just check !
I explained that quite fast, but i hope i gave you the idea, if you want you
can contact me at my email ( on Sunday i'll be off the list )

P.S. have a look at Allaire's Developer's Exchange, if you can run servlets
there is a servlet which insipired me...
