One of the many excellent presentations at the recent Arduino Miniconf in Wellington, New Zealand, was Justin Mclean's "Putting your device in the browser and on the web". Justin's talk demonstrated use of a Flash object in a browser displaying data acquired by an Arduino, and also controlling the Arduino based on user actions.
It was a really impressive demo because the latency was so small: in one demo, quite rapid analog samples were pushed to a dynamically updating graph that scrolled across the screen. Justin has put his slides and example code up on his blog. He's also doing a talk at the Web Standards Group in Sydney on February 24th, so if you're in town make sure you go along. He's a great speaker with some excellent tech to demonstrate so it'll be well worth it.
