Why does the Navy research onion routing? Only reason I can think of is so that .mil can study other sites anonymously, or communicate amongst themselves using anonymous-routing-tech to avoid traffic analysis. The other practical possibility is that they're happy to have smart CS people and will fund whatever they want to do, just to keep them. ------------------------------------------------------------ David Honig Orbit Technology honig@otc.net Intaanetto Jigyoubu "I actually thought Silicon Valley was where women went to get fixed." ---LA Mayor Richard Riordan 98.02.19
