Well, cryptographers had invented a fancy thing called "ring signatures" that allows one to check whenever a signature belongs to someone in a group, but don't allow to determine who exactly that was. So, technically, it's well possible to remail anonymous (as far as belonging to a group does not break your anonymity) and be trusted at the same time.

But, unfortunately, I don't think F2F mesh networks would prosper anytime soon.
