Maybe getting back on topic, what have the 300-400 or so prototype owners tried in terms of getting USB enabled? Not too long ago, people were talking about being able to force host mode via a software "TEST_MODE" flag. Any luck with this? Can anyone smarter than me (with or without a device) post a script for adventurous users to try?

Personally, I wouldn't feel too bad about having to carry around a little powered hub with some sort of batter pack hack to get this working.
