You guys are soooo behind the times.
In Oz we've got CPDLC and ADS. Had it for quite some years. On our ASD (air situation display) circles are SSR tracks, + signs are primary paints, squares are flight plan tracks, triangles are ADS tracks, and soon we'll have ADS-B tracks all over Oz down to F300.
Our ASDs can have all or any combiation of these tracks at any time. Mostly outside radar coverage, we'll be using either flight plan tracks or ADS tracks. this would be over our oceanic and trans-continental airspace sectors.
I believe NY oceanic sectors use a similar system as does NZ.
Oz also has a long range radar (Jindalee), which is not a secret. What we use it for, is however. It is a military installation not civilian and not used by ATC.
