How do we feel about content provider questions, such as Streaming video to Android? That one's a bit on the border -- it's useful for users to know whether they can stream video as well -- but clearly there will be some questions that aren't relevant to regular users.
I suggest a similar approach as with dev questions (as discussed in Development Questions: where to draw the line), where:
- User questions about how they can access content is on topic
- Advice on the "Android audience" or questions more about media tech than Android are offtopic
- Questions such as the example in this question where it's borderline are determined on a case-by-case basis.
I personally think the example is on topic.
