The Planet should develop it's own control panel that has all the features of cPanel, but it will support Apache, Nginx, Lighttpd. cPanel only supports Apache and millions of users around the world are now using Nginx and Lighttpd.
Currently there is no hosting control panel that supports both Nginx and Lighttpd.
TP should develop one that allows users to disable Apache then with a click of a button, allow users to choose Nginx or Lighttpd. It should run on Linux(redhat, centos, ubuntu, debian, etc), Freebsd, and Windows.
