Shared common fate --but that's a different thing, I think. If you specifically use a shared secret or something along those lines to break the chunks up, then I think it might be pretty hard to put the pieces back together. In this case, you might be able to use something like a "side channel" to send a one time pad that's used as a hash to break the messiage up, send each piece along a separate channel, and then put it all back together on the other end... Of course, this all assumes a completely new email transport system, and it assumes the server where the pieces are put back together is secure, or you use a more POP-like system, where there is no storage of the complete message on anything other than a local system... I think this is all possible/doable. The question is --is the world ready for a new email transport? Do we try and build it, to see if they will come?
