You alluded to this in your comments, one way is to provide an API key for your plugin, that way your clients are actually paying for support and updates and not code, it’s really one of the only decent ways to go about this. For example if their API key is not valid or expires they do not get access to your private forum or any plugin updates ( you would need of course to provide a API for a unique key, external update request and authentication).
