The plugin works very well. I'm doing a WordCamp talk on it and similar plugins like VersionPress and Revisr this weekend. WP Pusher is good for not only "cheap-ass shared hosting" (heh) but for environments where we the developers have restricted access to the client's admin. I'm thinking particularly of the one client who has 17k users on a multisite network with hundreds of sites, and the chances of us gaining super-admin access are, well, non-existent. We currently use a theme with Github updater built in, but WP Pusher will make it easier, and we can use (free) private Bitbucket repos as well. Use of repos in this way also allows us to reconsider our current deployment techniques, e.g. using dploy.io. Nice work Peter! We owe you an øl ;)
