Scoble asked:  "I'd love to hear your ideas on how to make small ISVs comfortable with doing business with us. Is it getting you legal help?"

How about something like a Public Defenders Office, but offering legal services to small developers? Think of it as a legal defense fund, with strength in relevant law, busines negotiation, startup organization, etc. Set it up as a not-for-profit, Microsoft funds it, inviting other industry firms and Darpa to join. Conflicts of interest? The lawyers can manage that. Basic benefits? Trust (more new relationships), speed (faster time to market), endurance (relationships persisting multiple encounters).
