Hey Andre

Great idea - theres not many people about who dont pay for their mobile recharges & piss it against the wall sessions

I think a lot of people would be interested to do it, the normal obstacle for most is having the cashflow to by one outright! The positive for it is that most would be able to do a periodic payment due to "enjoyment versus value".
It is already working in other countries so roll with your idea - make it real
