dd as an imaging solution.

Several months ago I was using Freesbie 1.x to dd a harddrive across the
network as a drive duplication effort. This worked 7 computers got the
image. I'm trying to do this again so I got the new Freesbie release 2.0
and fired it up across the computers and tried something simple such as:
dd if=/dev/ad0 bs=1m | nc othercomputer 10000 on the image provider
nc -l 10000 | dd of=/dev/ad0 bs=1m on the computer to receive the image.
I received an operation not permitted. My first thought was they must be
mounted. a quick check, and it seems they weren't.
Next, am I really root? And sure enough I was. After a bit of discussion
in #freesbie on freenode got me to set kern.geom.debugflags to 16 and I
was able to write to ad0 like I had previously done. Yet when I tried to
write to an individual slice I was presented with the same error.
Anyone have any clue ? The eventual goal is to have a mass imaging all
at once with dd, nc and tee
