Reminds me of a concept in the recent edition of the pen and paper RPG Shadowrun, all communications in the fourth edition is handled by a "commlink" which is a sort of combination mobile/cell phone and PDA with full access to its version of the internet. It's possible to get the menu for anywhere you go on it as you walk in, and it makes me wonder whether some time in the future something like that might happen... and if the device in question has speech or braille output then this would be fantastic.
It would also stop sighted people having to peer at the menu in places like macdonalds, or the staff worrying about menus being moved damaged or lost. They wouldn't even need to print that many menus except for the technophobic fogeys.
Suppose it would take a form of wifi that could either push files to wireless enabled devices (with permission from the device naturally), or else just advertise the file to anyone in range without them having to mess about with finding a network drive. Sort of a publicly available read only wireless FTP server, only one that is available without any set up on the client device.
