I would like to announce the immediate availability of my new plugin, Multisite Administration Tools.  The idea behind this plugin was to give multisite administrators an easier way to keep tabs on what plugins sites have enabled, or from the other angle which sites have a certain plugin or theme enabled.  The plugin is written to be run from the standard plugins folder, and requires network activation.  Enjoy!
