Sort of what carputer1 said.
The Standalone beta has this functionality, but despite a number of downloads there has been no feedback on whether it works or not.
I am also in the process of adding a registration process to the plugins so that don't have to be downloaded from my website (however users would still have to register on my site), ie I can upload them to the downloads here, they would be downloadable by sonics now defunct pluginmanager and people can share it around.
And I am trying to add a basic update feature to it.
Plus incorporate the new plugin code.
