I've had a Hotmail account for many years now.  I thought that was my Live ID.  Recently I was asked to provide my Live ID, and I gave the person my Hotmail email account.  He said, "No, give me your Live ID."  Huh?  Aren't they the same?  Or is it the case that one's Live ID may have a Hotmail account associated with it?  Perhaps more than 1 Hotmail account?  Maybe other email accounts that aren't Hotmail accounts?
