In a 72 page petition filed with the FTC, the DEA, FBI and Justice Department are teaming up to get the FTC to pass new wiretap rules that will allow for interception of internet communciations (WSJ, subscription only):

WASHINGTON -- The Justice Department is proposing that regulators adopt sweeping new wiretap rules for broadband Internet communications services. The proposal was triggered in part by the rapid rise of Internet telephony, which the Federal Bureau of Investigation fears could be used to avoid wiretaps on conventional phones. But the proposal goes beyond Internet telephony, asking the Federal Communications Commission to consider rules making all broadband Internet services more compatible with wiretaps. And the proposal seeks rules requiring that new applications and services on the Internet be wiretap-ready before they are introduced to the market.
