I wouldn't even attempt this in CF. You will have to use Java/ActiveX
Control/etc. for real time or near real time data due to the need for a
persistent connection. Take a look at LabView from National Instruments.

Subject: real time processing
Hello,
I've been doing intranet sites (mostly forms/reports) and lurking on the
list for several years now. Recently my clients have expressed a great
interest in real-time monitoring, so I'm a bit out of my league. We have a
WebDaq that writes a file every x seconds. I need to get the file, process
it, then display data via applets would be my guess. My first thought was to
cfftp-get the file, parse it, then send output to the applet. I'm not sure
this is going to be efficient enough to display data real-time (of course a
small time lag is okay). I know there are sites running stock tickers. Is
there a standard procedure for accomplishing this? Also, does anybody know
of a good applet library for controls like thermometers, speedometers, etc.?
