Google's been asking developers to submit demo videos for their Android apps for a few weeks, and now the fruits of that labor are starting to ripen -- a little bit, at least. Roughly 500 apps apparently have videos available through the Market's API, which means third-party app discovery sites can expose them for your perusal. What we haven't found, though, is a device that can see them yet -- either on the old or the "new" Market -- so it's not clear what the plan is for getting those surfaced (if at all) on phones.
