It might be useful for you guys if MC itself collected some of this data. It would, of course, have to warn the user. But I'd happily approve MC collecting some limited anonymous usage statistics. I'm thinking you could find out things like:
1. Precisely how many people are using Audio, Video, Images, TV, and Documents support.
2. What percentage of usage they spend in each category (mine would be HEAVILY slanted towards video, but others wouldn't be).
3. You could see the effect of changes on usage patterns. If you tweak something, and Image usage falls off the cliff, it might be a clue that you did something wrong.
4. You could also collect stats on things like Library sizes and mixes of different Media Types.
5. How often people are using things like Theater View vs. Standard View.
You WOULD, of course, need to be careful. I would NOT want JRiver collecting or transmitting details on my specific media content used, or anything of the sort (ala iTunes Genius). But, I would be happy to participate in a limited statistical sampling that would cover the stuff above, if asked, and if the details of what was being collected was clearly laid out ahead of time.
