I should point out, this is for replication in a running production
environment. Machines cannot be taken down, and swapping hardware is not
an option.
I'm currently experimenting with a copy of the MBR, and the root
partition on a CD, with enough tools to attach to the network to
retrieve images of the rest of the partitions (which can be taken as
current snapshots from various servers).
This _should_ result in the following scenario:
Boot new machine with CD
partition drive(s)
dump MBR
dump root
ssh [EMAIL PROTECTED] 'dump -C 64 -0af - /sliceX'| (cd /usr; restore -rf -)
[repeat above for all drives, could be automated]
Seem reasonable?

Now whether my details are a bit off, that's fine, I don't want this to
be diluted in to discussion of minute frivolous details (as these things
are wont to do), but what I _am_ looking for is a tried, tested and true
method of FreeBSD machine replication, specifically for the 5.3+
releases.
I have found the following paper to be incredibly usefull :
http://www.pix.net/software/pxeboot/archive/SANE.pdf
I used some of the ideas in it to clone machines in the 5.1-5.2 era.
You could also just mirror the drive with a Promise RAID 1 card. I've done
that a couple of times and it works really well.
