Since October last year the development was stopped. Only Oliver Dietzel, a former employee, has done some patching and found a way to get a stripped HotZone Up and running. Stripped means one 2,4 and one 5 GHz minipci card in the box. The box is far away from full functionality. But there are boxes in the market that can handle all the required stuff, maybe they have bought them?
For a real deployment you need many more things, i.e. roof rights or several towers, antennas, a stable power supply and many other things. I am missing the background noise. No Mexican statements, nothing. Also if they had 100 customers we would see a PR for sure.
