I stay in pretty close contact with the TechNet Subscription Program Management team. When I spot a product I think you'll want to test that isn't on the download area, I ping them and offer my thoughts. They are asking for similar thoughts right now. Head on over to http://blogs.technet.com/technetplussubscriptions/archive/2007/08/16/what-would-you-change-about-technet-plus.aspx and tell Kathy what you like and dislike, what you'd change, etc. This is a great way to shape the future of an already awesome resource.
