RE: [ISSUE-206] Service Provider (and related ISSUE-219 question)

Hash: SHA1


Thinking about Justin's concern, would you accept a friendly amendment to your service provider definition making it clear that data should not be shared outside the context in which it occurred (i.e. our definition of tracking), i.e. even if it is only acting at the behest of its contractee. 

(5) ensures that data about a user's activity collected in a context when DNT is set will not be shared with parties in other contexts.
