Enough already. Happy to be mentioned on Engadget, but this story seems to be getting more distorted with each degree of separation, as in a message starting out as "My brother has a new bike" ends up as "Your mother is an old dyke." So, for the avoidance of doubt, I never said there weren't security options to deal with this. My point was a bit more subtle, or at least I thought so. Stuart and Martin also have a lot of interesting things to say on the issue of presence management, which was really at the root of what I was trying to say.
