That's great...I have always said that even charging $1 for IT services between departments inside most companies would eliminate stuff like this, in your case the 'cost' was the extra effort and regulatory burden, and it quickly eliminated that which was not needed.

Read Dan Ariely's books on the 'irrationality of FREE' I find it applies directly to software and/or IT departments and the way they interact with their 'customers'
