An interesting and unsettling development on multiple levels. First, there
is the technical issue of whether the implementation is truly secure,
including whether information can be deduced from such activity.  Second,

amount of my paid for bandwidth legal and acceptable? An additional, and
perhaps more important question is whether such a feature should be enabled
by default. NOTE: The referenced article contains a number of web references
