Having spent the last couple of days playing with VoIP (Voice over IP) - or as one of our more technolgy orientated members pointed out on the Computer/Internet Issues corrected me 'voice over Internet' I believe I could comfortably make calls (God forbid over my laptop mike/speakers rather than headset) as soon as the already approved internet facilities become more common.
Banning the mobiles might reduce but won't stop the halfwits (or very busy business folks like wot I is).
