Re: Operation haystack...
Yep, been there and done that - since about 2006 (when I was slightly involved with sensitive GMO detection % levels and so the work called for a legitimate use of TAiLS, ToR & TrackMeNot etc)
it really annoyed the IT support at work, it didn't seem to perturb particularly the professional watchers, I guess that you do have to write your own traffic generators/mixers to avoid the backdoored complier type problem.
I think it is a very valid countermeasure to the commercial slurping, which is *almost* worse than the 'gov stuff, but as they are sovereign - they all are allowed to do whatever they want, provided they occasionally explain/justify, which is nice.
