Not necessarily. There's always public-private key encryption, which 
wouldn't be too hard to implement. Of course, now we run into the trust 
problem of receiving a server key over the Internet and all, but that's 
just being pedantic and not appropriate for this discussion.

I'd love to see the backend connection to the directory server being 
run through an SSL tunnel. Not being a programmer, though, I don't know of 
the scope of effort it would take to implement that. Something for Jack to 

The real question comes down to this: What is the value of the data we're 
trying to protect? Conceivably, someone could hijack the connection and 
send false data back to the directory server. Maybe just mess with your 
listing, maybe a form of DoS. Perhaps you might be able to inject 
something that would mess with the directory server itself. I think, 
though, that if that were the case, you'd be able to break things even if 
it was running over SSL. Sure, I'd rather have everything encrypted. 
Whether or not that's feasible, though...
