Fascinating paper. It seems that if you were to have a number of VOIP phone numbers (say a four or five different Google Voice numbers) and used different numbers for different services, it would defeat the correlation attack but you would also need to scramble other personal data (avatar Etc.) in order to prevent that from being used for correlation. Of course if you have access to the telephone network real time localization service[1] you could do correlation analysis that way.
