I agree, the namespace system could not be used in that fashion to contain the 
e-mails, but the private/public key structure of the namespaces make them 
ideal for encryption/decryption. Also, the mailbox owner cannot "delete" 
messages; rather, the messages would fall off of the network after a given 
amount of time. In GNUnet, nothing can be deleted per se.

Something like that. But namespace/updatable keys are Freenet's inefficient 
way of handling mail. Perhaps we can come up with something more efficient 
without sacrificing anonymity?

Agreed, very different. But probably more similar than mail and afs.

Agreed. That's like saying, "Why not just encrypt the desired content and post 
it on your website? Why do we need afs protocol?" Anonymity and censorship
