Ask YC: Startup School attendee seeks followup with Adam Selipsky

At Startup School, Jeff Bezos told me to get in touch with Adam Selipsky about getting an exception to the 100 Domain limit in SimpleDB (See http://omnisio.com/startupschool08/jeff-bezos ). Adam Selipsky turns out to be a hard man to reach. Does anyone know how I can get in touch with him?
