You can create a mirrored zfs setup, however, there is something to note. It is disk for disk mirroring at the zpool level so you create mirrored storage, not mirrored filesystems, and it is not possible to detach one complete mirror as the zpool mirroring forces a RAID 0+1 configuration.

For example:

Code:
zpool create mypool mirror c0t0d0 c0t1d0 mirror c1t0d0 c1t1d0

would create a zpool called mypool where c0t0d0 mirrors c0t1d0 and c1t0d0 mirrors c1t1d0

You would then use :
Code:
zfs create mypool/application

to create a zfs filesystem on the mirrored pool and
Code:
zfs set mountpoint=/applications mypool/application

To set the mountpoint of the filesystem to /applications.

ZFS Mirror versus Hardware Mirror

I've looked a little but haven't found a solid answer, assuming there is one. What's better, hardware mirroring or ZFS mirroring?

ZFSLOADER(8)						    BSD System Manager's Manual 					      ZFSLOADER(8)

NAME
zfsloader -- kernel bootstrapping final stage DESCRIPTION
zfsloader is an extended variant of loader(8) with added support for booting from ZFS. This document describes only differences from loader(8). ZFS FEATURES
zfsloader supports the following format for specifying ZFS filesystems which can be used wherever loader(8) refers to a device specification: zfs:pool/filesystem: where pool/filesystem is a ZFS filesystem name as described in zfs(8). If /etc/fstab does not have an entry for the root filesystem and vfs.root.mountfrom is not set, but currdev refers to a ZFS filesystem, then zfsloader will instruct kernel to use that filesystem as the root filesystem. ZFS COMMAND EXTENSIONS
lsdev [-v] Lists ZFS pools in addition to disks and partitions. Adding -v shows more ZFS pool details in a format that resembles zpool status output. lszfs filesystem A ZFS extended command that can be used to explore the ZFS filesystem hierarchy in a pool. Lists the immediate children of the filesystem. The filesystem hierarchy is rooted at a filesystem with the same name as the pool. FILES
/boot/zfsloader zfsloader itself. EXAMPLES
Set the default device used for loading a kernel from a ZFS filesystem: set currdev=zfs:tank/ROOT/knowngood: SEE ALSO
gptzfsboot(8), loader(8), zfs(8), zfsboot(8), zfsloader(8), zpool(8) HISTORY
The zfsloader first appeared in FreeBSD 7.3. AUTHORS
