This looks nice but it's missing one feature that's stopped me from adopting services like this after having tried a couple of them - let me download the VM!<p>There are I think two fundamental problems with remote IDEs. One is of course offline mode, and I don't think "sync your code later" is a solution unless it also lets you "test your code now". The other is remote resource restrictions that mean you can only use a remote IDE for <i>some</i> of your projects and still have to maintain a complete local environment for everything else.<p>Being able to download the VM means local hardware for projects that need more hardware, and <i>real</i> offline mode for people that need it. Going open source allows for this but it still leaves all the work of setting up each box which can be a real PITA (cloud9 is <i>very</i> hit-or-miss) and that can probably be monetized especially with the added benefits of remote access for when that is better or necessary.
Well, other than it not actually working, its fine. I click 'start editing' after setting up a box and it prompts me for a username and password.
