I think most people will be very unhappy if there phone battery is being drained and battery life shorted because their phone is being use to relay someone else's signal.
Transmitting takes a lot more battery energy than just receiving.

You won't need data on a phone soon anyway!!! Virgin and BT are both hoping to set up permanent wifi using all the boxes in circulation.... So you can use wifi data anywhere... The signal will be stronger so the batteries will last longer... The phone will only be needed for voice calls.. Wow won't that be novel!! The very worst thing about my smartphone is the ability to make phone calls!!!
