Some information here about licensing for DBPro from Matt Nunn. Hopefully he won't mind me re-posting here:
If you purcahse data dude it automatically comes with a full MSDN subscription. If you are already an MSDN subscriber then you can get Data Dude. If you are a Universal subscriber you can elect one team edition product when you renew your subscription if you subscribe to any of the lower tiers then you will need to purchase a team edition subscription
So that's good news. There IS a flavour of MSDN subscription that will allow you to get a copy of Datadude. OK, its not a cheap one but at least its an option.
