One of the questions that came up when talking about delivering Whidbey builds more frequently is distribution medium. DVDs are a lot more convenient for everyone (and cheaper for us). Suppose we made these DVD only? I imagine at certain quality milestones - e.g. an official beta - we'd make cd's available too. But for an interim build, would not having CDs block many people? I'm sure we'll find some data somewhere but I'm curious what people think.
