Our Plugin feature is now out of beta testing, and live on the newest distributions.  Upgrade your installation and here is where you will find it:

Developer -> FWS 2.1 Core and Custom Plugins

You now can use frameworksites.com to manage plugins and use this site as a repository for your plugin management. (Or you can do it by manually).   By using the configuration option FWSKey in your script file, you can then manage securely your plugin access for your clients sites, and then upgrade them remotely with an easy to use subversion system.    Thank you for all the help from our contributors to make this possible.  Cheers!
