I rolled my own little web IDE back in the day so that I could build out a PHP project while backpacking around the world. Part of that was a text editor that handled block indenting correctly and corrected for TEXTAREA's annoying way of dealing with doubleclicks to select text. It was actually pretty nice, traveling without a laptop and simply dropping into an internet cafe and firing up any browser to get to work. Naturally, the main issue was that you could only use interpreted languages like PHP with it. Django and Rails weren't even on the horizon at that point, so once I conclusively proved to myself that PHP is just not worth the hassle, I picked up a fast laptop and a copy of VS.NET and haven't looked back.
