It is possible . . . but expensive (at least on my budget). Generally, the applications that can use the scanner are limited, and it really is more of a PITA than it is worth. HP used to have one . . . (Scanjet 5 something something), might still have something, haven't looked for a while.
Xerox still has something that they push with their document imaging, but I'm not sure if it will do anything else. Plan on getting at least half way to six figures that direction (software, scanner, doc server).
Actually, you might want to price the Xerox deal . . . might calm Exec VP Brother.
