And key exchange is done how? What about re-keying and key generation?  Are
you using the same keys in both directions? What about authentication
(symmetric cipher based protocols are inherently vulnerable to active MitM)?


Cryptographic protocols are hard - one can't just "cut and paste, voila!".
This is why the authors recommend tunneling it over SSH, which is a protocol
which is peer-reviewed, under active development and made to be cipher
independant (so you can plug in AES, for example).

Wait! Smells like...Security by Obscurity!
