Lou Rosenfeld and Steve Krug roadshow.

They're each offering full day workshops in Washington D.C., Los Angeles, and Chicago. Krug's are the day after Rosenfeld's.

Lou's tackling the ugly problem of creating unified IA across departments and business units in large organizations in Enterprise IA: Because Users Don't Care About Your Org Chart and Steve offers Don't Make Me Think: The Workshop

I'm particularly impressed by Steve's comment about Lou's workshop:

If you're involved in a large, politics-ridden enterprise site (does the word “silo” ring a bell?), you owe it to yourself and your company to spend a day with Lou—even more than with me.
