If I may, Mr. Chairman, with regard to the question of being able to track, which I take it is what Mr. Andrews is particularly interested in, the kinds of logs we keep and so forth really are done...again, coming back to this business application support, it's a question of recovering for people who've lost things and want a record of them. It is to recover for the sender, for the MP's office or the research bureau or whoever, what they might have lost or what they might need for archival purposes.
So the approach, in terms of archiving and whatnot, is not one of saying that we want to systematically have a record of every communication in the event that we want to go back and forensically trace who said what to whom when. That's not what it's about. The purpose of it is to recover for people who might have lost their original communication, and that's why we've never explored the idea of trying the software you were talking about to track PIN-to-PIN numbers. That's part of the flexibility we give members, and it's up to members to decide how they want to use it.
