Great question, Torrey. The MMS is aimed typically at a removable media device such as a tape drive or optical disk platter. We leave it up the application to determine what it wants to write to, but we manage the mount, location, which driver to use, etc. As you mention, this would normally be in an enterprise environment.
However, we do have the capability to write to disk drives and address them as a "tape" device. The driver we use is called the dda, disk archive driver. I don't see why we couldn't write to these USB type devices using the same driver. And as you mention, is there code that can be leveraged for both projects? We'll check in to that and get back to you. If you have a pointer on the open solaris pages, I'd appreciate it just to save us some time.

(USB drives for example.) I've seen work in Solaris to make those sorts of devices easier to work with and, though I know enterprise tape and USB drives are different beasts, it would be interesting to see if there are any cross over points or areas for code reuse.
