AoE is like iSCSI. It provides access to a block device over the network.
Their example uses ext4, which is not a clustering filesystem, so you
can't have multiple machines mounting the same ext4 filesystem at the same
time. You would need a clustering filesystem like GFS to provides shared
storage that multiple clients could mount simultaneously.

Never tried it, but I would guess that shared storage would work for
sysvol. Though, I'm not sure what would happen if multiple users tried to
modify the registry on multiple DC's at the same time, I suspect
someone's
changes would get lost. Also, note that shared storage will emphatically
NOT work for the rest of samba, as the database is not identical between
DCs.
Still, it sounds like a lot of work to replace a couple of cron entries
for rsync. Note that by default the group policy editor will always
connect to the PDC, so unless you have admins purposely connecting to
other DCs, you really only have to worry about one-way replication from
the PDC to other DCs.
One other pitfall is that unless you put sysvol on a SAN or some other
kind of redundant storage setup, you are creating a single point of
failure for it. If your sysvol host system goes down, none of your DCs
will be able to serve group policy.
