NSA crypto at DNC?

http://www.nytimes.com/2004/07/26/business/26verizon.html "Nextel, the official mobile provider to both conventions, is deploying its iDEN network with encryption codes used by the National Security Agency to make sure no one eavesdrops on all the deal making." Anyone know what's up with this? I'm guessing this just means AES, or maybe Skipjack, but it would be interesting (and very strange) if they were using BATON or JUNIPER. -Jack
