The info wouldn't get into the bar code.  The idea would have to be that we
use the existing bar code as the key to a database in the PC.  The PC database
would have a list (maybe a start would be the GF Shopping Guide from the folks

isn't that hard of a concept.  The only draw back I see is that the equipment
you would need to take to the grocery store would be either really expensive
(laptop PC & bar code wand) or real combersome (lug a cheap huge PC around).
Technically it would be possible but ...
