i have heard of that storage area, but the latest i read on the ipad as a "productivity" tool indicated that the only ways to get files to or from the ipad, that could be accessed by apps while on the ipad, was itunes or email.

basically, no hooking the pad up to a random computer, copy some spreadsheets over, work on them on said pad, and then copy them back on a computer.

the storage area you mention sounds seperated from the rest by a virtual air gap...
