what about the possiblity of adding a named option and give the exif data 
in a read-only text string? the only problem i see with that is that the 
value of this option would only be valid _after_ the page has been 
scanned (ie- the length of an adf scan may not be known before scanning)

what parts of exif cannot be extracted from existing sane options?
