Cryptowi has a service that is actually needed in many 2nd and 3rd world countries where high speed mobile networks are still relatively expensive. Last year I had the privalege to travel to a few countries in East Asia and a couple in South America. All these locations had tons of wifi networks available that could potentially make for a huge user base considering majority of these countries still have expensive data plans.  I noticed many locals hunting open wifi hotspots everywhere I went.
