I actually made an WordPress Theme and Plugin update server based on this logic. While it does not block the plugin from executing, it does stop the auto update functionality which is crucial for any serious WordPress admin. You can see it here
What it essentially does is, when a client (your customer’s website) requests a token for a purchase code, then it records the domain. If it was registered for another domain then that is deleted and the previous domain stops receiving update. Both the metadata and download links are protected through a strong token.
