Feds want to wiretap push-to-talk

Guess the push-to-talk party is over: the Feds say they need to be able to wiretap those walkie talkie-type push-to-talk messages (they've been able to listen in on cellphone calls for years). The only catch is that right now right now the only carrier that'll actually be able to do push-to-talk wiretaps is Nextel —Verizon, Sprint, and Alltel all say that they don't have technology set up yet.
