Sending GIF images is not a good idea for several reasons 1) If the display updates once per second, you'd need to send an entire GIF image every second, 2) What if the user has a very small screen, like a cell phone, or he has a large screen? The GIF will either be the wrong size or you need a way to tell the server what size image to make 3) How to zoom and change the image scale? Again all the heavy lifting must be dome on the server side
THis is backwards. I'd like the monitor to run on very LOW-END hardware, like a PIC, AVR chip or whatever and hopefully without even the need to boot an OS. One way to move data from a monior to a display is SNMP http://en.wikipedia.org/wiki/Simple_Network_Management_Protocol This can be implemented with a very light weight process and not very much data moves over the network. Also display programs that run on the desktop computer already exist. It is easy to query and plot SNMP data. So makethe Thunderbolt look like an SNMP device. SNMP implements commends that i effect say "get me the temperature data for the last N hours." or "set this parameter to this value". It is exactly what is needed and we don't need to write the client side software. Unless you'd want a custom display. I think the monitor should be able to run on atiny uP, something that cost $20 or so and use very little power, under 1W.
