As sdiz pointed out, it's unlikely that this would buy very much additional 
protection. On basic freenet, the chunks are encrypted and you can't 
reasonably be expected to know what encrypted data corresponds to what actual 
data. Except if they try to show that you have *all* the chunks of a specific 
file and therefore have probably downloaded it, which is possible even with 
XORing. Oh and btw, the last chunk DOES carry data derived from the 
original - a chunk of the original XORed with two randomly picked chunks. And 
then there's the question of finding the chunks in a way that doesn't give 
away your location, which is not insoluble, but would be a potential source 
of attacks.
