Deploy spark plugins to exisiting users

Is there a built-in method to deploy Spark plugins to existing Spark users? If not what are people doing to deploy plugins after the client has been installed? Scripts or group policy would be my guess but thought I would ask instead of trying to reinvent the wheel if this is the case. Thank you.

Most plugins are server side and require no installation on the client. If you are talking a true spark plugin there is no deployment architecture.

Yep, this would be a client side plugin. Trying to deploy the whiteboard plugin from version 2.
