Hi Peter, Thank you for posting in windows server forums For licensing questions, I suggest contacting Microsoft Licensing Center for detailed explanation. http://www.microsoft.com/licensing/contact-us.aspx please call 1-800-426-9400 (select option 4), Monday through Friday, 6:00 A.M. to 5:30 P.M. (PST) to speak directly to a Microsoft licensing specialist. Worldwide customers can use the Guide to Worldwide Microsoft Licensing Sites http://www.microsoft.com/licensing/index/worldwide.asp to find contact information in their locations.

Yes. See: https://technet.microsoft.com/en-us/subscriptions/securedownloads/dd464803.aspx#ProductKeys.I have used the same key for Server 2008 multiple (at least three) times.I think the number of times you can activate depends on the product/key type, and the level of your technet subscription.
