    I don't see why not, but I also can't think of an application where we
    would want to do that.
What if the journal is for an encrypted disk?  It would probably be 
desirable for the journal data to be encrypted in that case, especially 
if the stream was a socket to an offsite machine.  It might be necessary 
to store key data in the journal; depending on just how the encryption 
is done.

(Sorry if this sounds like I'm playing devil's advocate.  I really meant 
to ask this question earlier, but I didn't really (and don't now) have 
the knowledge to ask it in a more detailed/helpful manner.)
