Don't the various methods of attaching to a remote desktop work well enough? I sometimes work in an IDE remotely on Windows using the native RDC or just VNC. Works great, smooth and fast, I would be happy to work that way for a couple of days if I was without my own machine. I don't see a big upside to sinking huge time and effort into a Web IDE when remote desktops fill most of the important use cases.

Also, how many developers are you thinking will be sharing the server using a Web IDE? For any compiled language I see compilation steps as big CPU hogs, severely limiting shared usage. Even with interpreted languages I suspect there would be CPU-sharing problems. Again, remote desktop seems a better solution.
