I actually did it for a while. I started my career in biotech and worked on an instrument. When I told them I was moving they wanted to keep me on and sent a couple of scanners to me.
I do realize that's a special case. They knew me for eight years prior, not nearly the same thing... but I thought I'd ask. There may be a fair amount of work that can be done via simulation, or applications level stuff, but yeah, a long shot.
Isn't the main reason for the ban the fact that they were worried security checks would be unable to detect bombs in devices like laptops in the first place?
