[AusNOG] wifi phone calls

Hi

So I saw this whilst I was reading Slashdot.

This got me thinking, if you took money out of the equation and politics (sic).  Would it be better for use to have a completely wifi wireless network, get rid of the mix of technology and just have devices that do some sort of VOIP.  I am presuming running an IP network is better than a GSM/3g/4g.

How much better would that be ?
