Dragon Age 2 - DRM Explained - EA account needed

Chris Priestly  just made a post regarding the DRM  used in Dragon Age 2. No disc check, you'll need an EA (same as the Bioware) account. And most interestingly is this bit:

- You can play offline but the game will require a login check after a select period of days.

Release Control (does not use securom)
      . It does not install anything to the PC.
      . Sole purpose is to check with a server to validate whether the game release date has passed or not. 
      . It completely removes itself after the game release date has passed. 
      . You will not be able to play until that date has passed.
      . Dates & times are set to the retail street date per country.

Apparently EA and Bioware decided to do something about retailers sellng the game early by this 'release control'. What do you think? Is this a good idea? or maybe not? And it is a good idea to have the game demand that you log into your account, when you play offline after a select period of days? No words just yet on how many specific days will have to pass, though.
