IMHO Plain and simple that WOOSH is CRAP.
Latency is high and unreliable.
Latency even in a wireless networks should not be so high.
Woosh won't make money, and is not viable without people investing millions just to keep it going. Pouring money into a big black hole.
AFU...
I would recomend that the investor in Woosh cut their losses now.
Pull out while they have only invested 10s of millions. Each.
