Thanks Matt, I'll have a look at GEOM gate but will most likely have to
wait for the NFS support.
If anyone needs any help testing the NFS Server work I'll be more than

under the 'Desired Features for 5.3-RELEASE' section:

So the only possibility for ACL support over NFS is going to be a 5.x
release, but seeing as it hasn't been included yet, probably not
One possible route around that would be to use GEOM Gate -- that's a
system rather like iSCSI or Linux's DRDB, where the server exports a
disk device, rather than a filesystem. This is a standard part of 5.x
now, and will be in 5.3-RELEASE, but it's still very new, so test
carefully before putting it onto important servers.
A FreeBSD 4.x machine should quite happily use a 5.x machine as a NFS
server. FreeBSD 4.x has no support for GEOM Gate though.
