In the East Africa US Embassy bombing cases, communication between operatives and 'middle managers' and bin Laden would consist of packages and notes written to one person containing contact numbers for another, who in turn had info to contact yet another higher-up member of al Qaeda.
al Marri of 'second wave fame' had a tunk shipped to the US with him which the FBI thought to be very interesting.
Atta also mailed a package back to the middle east right before his human cruise missile trick.
And then there is this- mailing 'seeds.'
"He [bin Laden] was a busy person and had hundreds of people working for him," said one El Hage family member. "You didn't get to see him unless he invited you." El Hage's mother-in-law received letters from El Hage that contained seed samples from the Sudanese farms. El Hage frequently took international trips to Europe and elsewhere on business for bin Laden, family members say. -"A Portrait of Wadih El Hage, Accused Terrorist," by Oriana Zill, Frontline, PBS.org, http://www.pbs.org/wgbh/pages/frontline/shows/binladen/upclose/elhage.html.(Oriana Zill was Associate Producer of FRONTLINE's "Hunting Bin Laden")
It's worth noting that Iraq had heavy influence in Sudan when bin Laden was in the farming business.
The entire family is dressed in American style clothes. It almost looks like an Easter Sunday picture as the little girl has a hat on similar to what one might see on Easter Sunday. So she played "I'm and American" for a long time. I'm more suspicious of her as hubby's helpmate. SHE has mideast connections AND knows several languages.
Mayfield and the sniper's lives run in parallel tracks. Where were the Mayfields on 9-11 and what were their comments?
