I'm in a hurry guys, so no time to see if anyone has posted any info on this...but here's a link to info on a conference that was to be held in Aug 2003. Could this be the one? Was Berg said to be in the US at that time?

There is a pop-up window where you can see companies that attended. I didn't see Berg's company. Did I miss it?
Here's this from another thread.
Moore's crew shot the 16-minute interview with Nicholas Berg during an Iraqi business conference in Arlington, Va., on Dec. 4, said his brother, David Berg.
A different conference?
