Michael Cote at redmonk has brought this up a few times this year. Most recently, <<a href="http://www.redmonk.com/jgovernor/2011/06/24/ide-as-a-service-daas-hawt-and-some-enterprise-opensocial-thawt/>" rel="nofollow">http://www.redmonk.com/jgovernor/2011/06/24/ide-as-a-service...</a>;<p>Truthfully, I don't know that it's going to <i>kill</i> conventional editor or editing habits (and by the time it does, I suspect that web-based IDEs will look significantly less like today's web-apps than they do today) and more that this technology will find a niche in code review, or version control interfaces, or something like that, but it's a nifty idea.
