Playing around with a spare wireless router (WRT54GS) I have, hooked it up to a stand-alone PC to do nothing except spit out MP3's, and started thinking: why isn't this more common?
What I mean is, using wireless as simple stand-alone information-spitting "boxes". No internet and no local network except for connecting users. The boxes would do absolutetly nothing except spit out information on demand. They would be read-only.
Places where this would make sense:
- Movie theaters: spitting out show times.
- Airports: spitting out flight/gate info BS
- Retail stores: spitting out "flyers" of current sales
Etc, etc. You can think of a million other places where it would also make sense.
Perhaps there are places in your area that take this very simple approach, but I've never seen anything around here do this. It would take practically no overhead at all for them.
It used to be that it wouldn't be too practical since not that many people carry around PDA's, but many people have Smartphones now...
