I have not paid a lot of attention, myself. The WiFi price/performance
ratio is favorable to community wireless. I don't think we know, yet,
whether WiMax will have such a favorable ratio, but early indications
are that the volume of WiFi sales will always be orders of magnitude
larger than WiMax. I believe WiFi's price/performance ratio owes a lot
to that volume.
One advantage WiMax may have over WiFi is that it is designed
for the kind of multipath events and propagation delays that one
WiMax is a layer-2 standard. CUWiN has done scarcely any work at layer 2.

I have the feeling that with polling, we would pay with some throughput
(due to polling overhead) for a benefit in medium-access fairness.
I don't know whether we need that on any operational CUWiN network.
