GSM suppliers working on that already and implementing softswitches in order to increase capacity and lower cost. However GSM is circuit switched - not packet switched (except GPRS) and here is the point cost can't really dropped.
The way it will be more probably is that GSM CDMA might be used in the furture in the suburbans and in metropolitan areas we will see a WIMAX/VOIP scenario. This will result in a hybrid network for at least a transitional period. We already experienced it with AMPS/TDMA to GSM transition. CDMA (spread spectrum) is almost dead because high cost and leck of roaming capacity. WCDMA/UMTS (spread spectrum 3G) is very expencive and hard to manage (in Europe the launch was delayed by 2 years because hard and software problems).
I recently started with a project (small scale) to setup such WIMAX based networks. The aim is to develop a low cost internet/phone network for rural communities in third world countries. Anybody with routing experience who wants to join me on a professional base is welcome.

That's interesting to hear. I thought wimax equipment was too expensive at this point for such a deployment scenario?! g-)
