I agree with you. Even using differnet keys for the various chunks wouldn't 
help much from a cryptographer's point of view.
An interesting variation, though, may be to send the information through 
different routes altogether.

For example I could encrypt a file, encode it so as to leave out a small but 
significant portion, send the large part to you through my main connection, 
then connect directly to a modem of yours and send the other part.
It would be hard for an attacker to monitor two defferent media and a file 
that is not only encrypted, but incoherent, would be really hard to decode.

This technique isn't new, but I've never seen it implemented in open source 
tools.
