Hey, I would be willing to host one in Invercargill, New Zealand, near Invercargill Airport NZNV.
We don't have a lot of ADSB traffic down here, but AirNZ is introducing some new ATR-72's around the middle of the year, and these will have ADSB onboard. We mainly get ATR and Q300 traffic.
As far as I'm aware there's no online coverage down here at all, be it AirNavSystems, or others such as flightradar24.
I should also be able to get approach traffic into Queenstown and Dunedin International Airports, both uncovered as well.
I'm a radio amateur (ZL4OM) and a general geek, so installing is no problem.
