Yeah, that's correct, paramiko doesn't tie into any other  
executables.  The idea was to be a pure-python implementation (except  
for pyCrypto, which I incorrectly assumed was on track to migrate  
into python's stdlib).

But I'm happy to support using only the sftp layer, like bazaar does  
if it finds an ssh executable.
