I don't believe so. Purchased content is encrypted with DRM which Infuse cannot decode and then stream. Pointing Infuse to the iTunes folder on the MacMini would not work because of the DRM content within said folder. Infuse and Plex have no ability to confirm the legitimacy of your Apple ID purchase thus allowing them to subsequently stream the content.Would it work if I purchased a MacMini, setup the MacMini’s iTunes folder on the NAS, and then pointed Infuse to the MacMini?
NAS is good for content that is not DRM protected, such as movies, tv shows and other videos that are not locked and can be played outside of a stock Apple app.
