If I really needed the extra speed, it would probably be better to spawn a
netcat over ssh so I don't have to modify the target's sshd_config.  I
played with the ciphers and arcfour128 seemed to give a marginal increase
in speed (could be measurement error though).

 It probably is ssh, considering the speeds I have seen on local
send/receives.  However, I am happy with 70MB/s for now, since zfs send
effectively eliminates the rsync filesystem walk overhead (which I was
using previously, and it had grown to something like an hour to walk it).

Anyway, enough with me hijacking the topic, back to Sebastian's problem.
