Like mdawaffe said above: Probably not. There's a lot of custom code talking to two different servers via http, cron jobs, svn actions and a dozen other things.
/Me guesses there is TOO much stuff going on behind the scenes, to even want to consider making this a "plugin" per se.. =/
I understood that, was aiming to some pluginmaster that want to created something like this :)
Well it aint that important, it would be just handy. Even more if all the info could be pulled (with some filters) so the plugins would stay at 1 central point (this site) and updated to. So no different plugin versions on every site....
Well just some suggestions...
