Currently in private beta, developed by Fog Creek, comes a online IDE for web applications, with deployment, hosting and team collaboration built in.<p>It reminds me how Heroku started (in 2007, 2008) with an online IDE for (only?) Ruby on Rails applications. Later, Heroku stopped with offering the online IDE and moved to the current deploy-via-git-push-model. It will be interesting how this works out for HyperDev.
