FBI retires Carnivore

SecurityFocus tells of the FBI retiring Carnivore, a customizable packet sniffer that is part of the Dragonware suite. Written in 1999, it was the third generation of packet sniffers, with the previous one called Omnivore in 1997. The first generation is thought to be based off a well-known commercial program called Etherpeek.
A Windows NT/2000 system base, documents have been shown that the FBI has not used this tool in 2002/2003 at all and in place used a undisclosed commercial piece of software.
Carnivore itself has been the hot topic for a number a years, due to the nature of infiltration of privacy, and how the FBI could use this tool alongside the 2001 PATRIOT ACT that is stated by the Security focus article:

Under section 216 of the act, the FBI can conduct a limited form of Internet surveillance without first visiting a judge and establishing probable cause that the target has committed a crime. In such cases the FBI is authorized to capture routing information like e-mail addresses or IP addresses, but not the contents of the communications.

Personal note: While this is interesting, Carnivore has been side-stepped by hackers of many generations for better tools (all Unix based). My question is: Will the rest of the Dragonware Suite be retired, and what commercial software is the replacement? Perhaps there’s a new version of DIRT by Codex Data Systems that is being used.
