Absolutely. Note that you can do similiar things via NFS mounts:I separate the namespace from storage type. See http://multivac.cwru.edu/fs/ (mind the trailing slash) for the original idea.

...clients mount pong:/export/Solaris (or whatever), and the symlink will cause them to access the actual file location in /Disks/dXX, which are a set of DiskSuite RAID-1,0 metadevices, similar to vinum. This way, I can move large trees of stuff between filesystem locations in order to balance space of I/O utilization, only change the symlink, and not have to change any of the clients or take anything down.
