I was in the supermarket this morning and I thought 'cell phones can transmit quite a distance... (however far it is to the repeaters), so why don't we modify some phone software (we'd probably need someone like NokDoc for this) and have some way of transmitting between phones that are only a short distance apart? What I mean is, why don't we program a phone to be able to communicate with another phone without the repeaters? There would be a range limitation, but you could have free calls and SMS!!!

I know it would be a lot of work... and maybe phones don't have enough spare memory to program something like this in... But I thought I'd throw it out into the NFree world anyway...

What do you think? Could it be done??
