Washington DC suspends fiber ditching for two weeks

From the Washington Post: "Mayor Anthony A. Williams ordered a two-week moratorium on cable construction under District roadways yesterday, hoping it will give his administration time to take back the city's carved-up streets from telecommunications companies."

I've been asked to moderate a panel about fiber cuts and the Internet in the fall. I would like to include a participant or two from the new carriers about what steps they take to prevent construction from damaging existing fiber from other carriers. And then what they do to protect their fiber from the next competitor installing fiber in the same street. Anyone from Broadwing, Level3, Qwest, etc?
