I'm playing around with creating an App Exchange app that has a chrome extension component.  The idea is to use User-Agent flow and a connected app to allow the extension to authenticate and then use rest endpoints to send data from the extension to the org.  Is that the best way to do this?  If I went that direction, would I have a single connected app hosted on my personal Org (for the client_id)? or include that as part of the salesforce app?  If I included the app in the package, would I have to make the extension user type in the unique client_id for each org's connected app.?  That seems like an extra step for the user opposed to a hard-coded client_id in the extension.
