First, I do apologize for the cross posting, but this came up in the
enigmail mailing group. It's off topic there, so I'll ask my question
here. Second, I do apologize for not trimming this message, as this hold
his original questions/situation info.

For this user's situation, would it be better to have each individual
have their own key signed by a company root key? Or is there another
model best suited for his needs?
