It's pretty early to make it seem like this is a done deal, from page wo in the article:

"Because the researchers weren't able to test their techniques on real-world systems they don't know for certain that they could thwart a wiretap. But Sherr believes that "there are definitely dangers" in the way the standard is written. "Because it's a black-box system, we don't know for sure."

And besides that, I don't think this will have much practical value. If you're aware that you are being tapped you'd stop using your phone and if you are not aware you're being tapped you are also not going to ddos the exchange-feds connection.

The not-so-smart thing to do is to alert the feds to the fact that you know you're being tapped by dos'ing them.

Did anyone find a free copy (preferably PDF) of J-STD-025b?
