If you were hoping to get your mitts on a download of IE7 B1 to play around with, you're SOL unless you're an official beta tester or TechNet subscriber.

"Contrary to some expectations, Microsoft says Internet Explorer 7 Beta 1 will not be publicly available for download. Only invited beta testers and Microsoft TechNet subscribers will be provided access to the bits. The company did not say whether a public beta would follow, and has no timeline for a final IE7 release."
