Enginetron looks like the better approach compared to Neon Control Panel http://neonpanel.com/ http://neonpanel.com/ which is a ground up rewrite of a control panel for nginx. Incidentally, what the general value of these control panels? Isn't it just a shiny ui on top of command line tools? Why is it that cpanel thrives while open source ones wither? Is it because there's some ongoing support issues?
