Once again the FBI and the Justice Department efforts to wiretap voice conversations carried over the Internet is making news. I briefly talked about this last July when the same thing came up. Obviously the feds want to keep this in the news.
Others have mentioned this item and hailed it as important and valid in the name of Homeland Security. Security and public safety are all well and good, but like most attempts at making things better in the name of Homeland Security we are jumping to conclusions about its effectiveness and effects.

What’s a bigger concern for me is, first, that here we go again with the feds promoting something and the public and many ‘experts’ accepting it without question to the effectiveness. More tax-money dumped without anyone asking if the ideas being proposed actually addresses the public safety issues or whether perhaps, in reality, it does more harm than good, like any number of the plans proposed (and many laws adopted) in the wake of 9/11.
And then there are technical issues, which are not just geek fodder, but which lead immediately to economic and social issues, that people that should know better are simply glossing over.

- Pure SIP is intended to be a peer-to-peer technology, where the VoIP providers don
