Introducing the closed payment system API into other applications is the next logical step. Getting more payment processors to accept ICG will create new opportunities to incorporate existing development in to new uses. It will also open up access to more merchants who indirectly accept crypto-currencies through use of a payment processor.
A community effort to increase acceptance of Incognito coin has been on-going and yielding succuss in merchant adoption. Although there's not neccesarily alot of businesses that accept alt-coins to begin with but web merchants will.
Fair point. It would be better to search for businesses and create a list containing potential merchants to contact in regards to accepting ICG. Hypothetically even dark-web merchants could be contacted but typically they won't reply back.
