Worth checking but not critical.

Right. Well, if it's not going to happen naturally, it's an exploit, but AFAICS 
it's not a useful exploit, right?

Thanks!

Oh, on crypto, we could go half way: Switch to Rijndael 256 key /128 block 
(because it's more standard), and CBC (because CFB/PCFB has some 
vulnerabilities, and because it's more standard), and always pad to a multiple 
of 16 bytes. Or maybe that's a bad idea since it would mean we can't generate 
packets of other sizes, short of ciphertext stealing? I guess we should 
postpone the decision. Filed a bug:

I am hoping to get this all sorted out as soon as I get back to work after 
Christmas, probably around the 28th.
