We have a pretty robust storage evironment though. We are heavily storage centric though so we have mulitple NAS heads from Bluearc.
We have production NAS storage backed up to a seperate nearline NAS storage head which is backed up (in pieces and on demand) to a Storagetek 143 Slot/4 LTO2 drive tape library managed by Veritas Netbackup.
I really like the Bluearc www.bluearc.com technology. They are the fastest out there and have the ability to manage a contiguous file system which is good and bad. The upside is that I could build a single share with as little as 3 Terebytes or as large as 256 Terebytes and theorhetically as large as 1 Petabyte (if we had enough money).
The downside is that since it's a CIFS file system I don't have the ability to quickly back up the entire volume nor can I get properties very quickly for any folder of any size. i.e. it can take a long time to enumerate a directory that is 300 or 500 GB in size as our particular directory structure can go hundreds of thousands of files and folders deep.

If you want to see the future of the SAN, study the history of the LAN.
Right now, SAN routing is just being introduced, and most SANs are fundamentally islands in a datacenter interconnected, if at all, by either proprietary links or through gateways to a corporate backbone. Sounds a lot like the LAN of about circa 1992-93.
If you want the metaphor for storage, look to a moving company. They have been moving and storing stuff for, let's say, hundreds of years. Stands to reason if you are going to store something for somebody, they may also ask you to move it for them as well. After all, you have posession of the data don't you?
We need IP routing directly from the SAN chassis to an IP network, for application data movement, for backups, and for replication among locations, for starters.
