Sorry for my english.
We are studying a new project of a AR service, that we hope... a large number of markers to manage.
In base of that we are asking if there is a solutions to manage all on our server ( SDK ? ) or if is possible to have an agreement with us to prevent eventually problem due the stop of the cloud service.
In our mind our service should be work for years and years and we want to be sure that we can supply the service continuosly.
