Long introduction not required: I give you Jobsinpods
People get audio files from jobsinpods with career info, employer details (what’s it like to work at acme, values, testimonials) and actual job openings, that can be listened to on their iPods or mp3 players whilst on their way to their soon-to-be ex-employer 
Flipside, it provides a mobile channel to agencies and employers interested in marketing to potential candidates via alternative media (you noticed how many people with earplugs on the train, ferry, streets - right? there you go)
