AutoCAD LT :: Sharing One Account On 360?

We would like to be able to store all of our drawings on the Autodesk 360 cloud but have two users in different locations and want to share a common account.  We already have two separate accounts with our 2004LT but that requires each of us to set up sharing for the other, notification, etc.  If we purchase two seats of 2013 AutoCAD LT can we both use the automatic save (to 360) with the same account user name and password?  25GB of storage with one subscription is plenty for our needs but the main objective is that all of our files would be in the same account and there wouldn't be any chance of us having slightly different versions of the same file in two different accounts. 

If one guy is logged into the account will that prevent the other from gaining access until the first one signs off?  I saw something on Autodesk's site saying they were working on being able to combine cloud units but they don't have it yet.  I don't know if this would also allow combining separate subscriptions?
