Well, not exactly. One can use kill -USR1 <PID of dd> to see the current
progress report.
dd if=/dev/sda | ssh root(a)192.168.196.129 "dd of=/dev/sda bs=16M" &
dd if=/dev/sdb | ssh root(a)192.168.196.129 "dd of=/dev/sdb bs=16M" &
dd if=/dev/sdc | ssh root(a)192.168.196.129 "dd of=/dev/sdc bs=16M" &
dd if=/dev/sdd | ssh root(a)192.168.196.129 "dd of=/dev/sdd bs=16M" &
and if shell pipe is used, pv can be really useful, use it like this:
dd .... | pv | ssh ....
and you'll get a nifty speed report, that corresponds to the rate at
which ssh reads from pv's output (~network throughput).
IMO pv can be used for local dd use as well, just do:
dd if=/dev/sd<source> bs=16M | pv | dd of=/dev/sd<target> bs=16M
