Semacode is an open system for generating url encoded barcodes (not the standard striped variety, but the square crossword puzzle-ish variety) for any url you want. Mobile phones would then be able to use these to connect with resources.
This would be interesting as a way to connect library items and handouts with related websites. The possibilities are limited at the moment since it requires someone to have a web-enabled mobile phone with the software installed, but there is a definite potential to this.
It reminds me a bit of the CueCat, without the commercial lock-in and resulting controversy.
