An encryption is only as secure as it's key. The keys used to encrypt
the data stream are generated on the fly and rekeying may occur
frequently in a session. Just keeping track of all of these keys
seems like a lot of work for not much benefit.

But, like I said, if you want to make a backup subsystem I doubt
anyone would object. If you release it and it's handy I'll use it
too! :)
