Great post .. quite a few new ones I haven't heard before. We were curating a similar list before a hackathon, and couldn't help wondering if there is a distro/vmware image that specifically targets web-dev - just ready to go with tools for @dot_cloud, appengine, heroku, all browser comparability testing - all rolled in. You know like backtrack, but for a web developer ... Anybody know if such a thing exists?
