Plugin Plugin

The plugins should be ordered in 2 folders inside "plugins" directory: "enabled" and "disabled". so to enable a plugin all you'll need to do is actually to copy a plugin from the disabled dir to the enabled dir.
therefore, is it possible to make a plugin that will have the next features:
plugin enabled - to have a list of all the enabled plugins
plugin disabled - to have a list of all disabled plugins
plugin enable <plugin> - to enable a plugin that is located in the "disabled" dir.
plugin disable <plugin> - to disable a plugin that is located in the "enabled" dir.
plugin get <address> - to wget a plugin and extract in on the "disabled" dir (for security reasons).

of course that all of these options are for admins only.
