Currently there is no straightforward way to detect Adobe Font usage in a document. There needs to be an API to determine which fonts are used in the document (exists) and of those fonts which of them are auto-activated Adobe fonts (does not exist). In addition, it would be great to expose an method for forcing Adobe Fonts used in the document to be activated, and for monitoring the status of the activation. Of course, you can enable auto-activation for the document to trigger when it is opened, but this seems somewhat unreliable in our experience, and in any case there is no method to monitor the state of the font activation, so the plug-in does not know when the activation has been completed.
