The Indigo team has created an email address to send all questions for the Indigo Panel at last day of the PDC.
From Don Box's Spoutlet:
Yasser set up an email alias to collect Indigo questions starting today. The email address is indipnl@microsoft.com - feel free to fire off those burning questions and we'll do our best to answer them on the 30th. In anticipation of the obvious two questions, here are their answers: Q: Will you make the answers available to people who can't make it to PDC? A: Yes - we'll post the Q&A somewhere conspicuous soon after PDC (I'll blog the exact URL once it goes live). Q: Why are you relying on this crufty email-based technology for collecting comments? A: We want questions from people who wouldn't know a web service if it kissed them on the lips. Asking people to consume WSDL to tell us they think consuming WSDL is too hard seems rather odd.
