Apple’s QuickTime Streaming Server doesn’t have much of a UI, but there is a fatally stupid design flaw in what little it does have.
You run the UI in a web browser. I use Apple’s own Safari for my web browser (I actually use several different browsers, but I use Safari for administration tasks for some reason). To get fresh data, namely stats on the “server snapshot” page, you need to refresh the browser. But here, have a look at where the geniuses at Apple put the “Disable Server” button… note the proximity to refresh button in Safari!
Tonight, while a good client was “live” and I was providing stats via iChat with their production staff… I accidentally clicked a few pixels too low and shut down the server. D’oh!
In my defence, I am test-driving a new mouse (an Apple Mighty Mouse btw) and my clicking is not as precise as normal, but still. They should put that “stop server” button somewhere else, don’t you think?
